Hello! First thing, I apologize for my English. It’s not my native language but I will try to correct as many grammar mistakes as I can 
Just bear with me please!
Okay so, after 80+ hours of gameplay I’m finally ready to give you my honest opinion/feedback about the game as well as my personal opinion on some things.
Classes:
So, my first big issue was sadly with the class change. It was kinda my mistake as well, should have read the forums or just simply ask some players but still. Description of the classes IN GAME are just terrible. All you see are some skills, how the character will look in the outfit and the “type”+“difficulty” of the class. Nothing else. So I was VERY disappointed (and sad) when I found out that after I swapped from Peltasta(3rd rank) to the Cataphract, I won’t be able to learn how to use One Handed spears… I know, You will say that “But it says that they are using TWO HANDED SPEAR DUH!” But hey, if you can wield Two Handed spear, then you shouldn’t have problems with handling One Handed Spear… So I kinda wrecked my build duo to the lack of information during the class change. We need some kind of in-game wiki about what classes can learn and things like that.
Another problem with classes, which is connected to guilds and community.
Yo have to sacrifice one rank to get a guild master, ok fair enough, one rank is not that bad… But why does it has to be the last one?! I’m an casual player, have couple of friends playing with me and we wanted to make a guild for ourselves and/or people like us. Casuals and/or Role Players. (You know, full time job, kids, responsibilities and things like that keeping us from soaking into the game more that couple of hours each day, sometimes not even that :P) But sadly, one of us would have to grind, grind and grind for ages just to get to that point, because the guild class is a RANK 7 CLASS. Not only that, it’s also limited to Swordsman class which is really annoying. So maybe it would be a good idea to drop it to rank 5 or even 6? I’m not a hardcore player and I won’t be one simply because I don’t have time, so why punish casuals?
Now, lets drop the classes topic and lets go to a different topic.
Trading system… Sadly, it’s a big failure in my eyes. I started playing with few people, we were leveling together, but then, when someone dropped something that could be useful to someone else in our group, we simply couldn’t trade it away… Trading system is a BASIC OF MMO games. I was really pissed off when I learnt that I had to get a token to do that… That is just milking people of money by making them buy the tokens. Not cool man, not cool… Another problem. Non token players can only put ONE item on the trading post… Again, punishing casuals. It’s not really worth it for me to buy a token if I don’t play every, single, day and I’m getting punished for that by restricting my gameplay.
Mail system. Okay, this one is precious. Sending an apology items via in game mail BUT only for a limited amount of time. So basically, I received in game mail with items, COOL! Thanks for thinking about players! But then, when you know, time to get to work so two or three 12 hour shifts later, I finally found some time to get on TOS, Great! I will use the EXP TOME, I will get my FRIENDS, will do some quests, or grinding! AWESOME! And what I found out? The mail is gone and so my items that I didn’t redeem… ARGH! Shot in the heart…
Drop Rate. Ugh, this is tough… Again Hardcore players will say that there is no problem since they have all the time to grind some items/mats or money but hey, I’m a filthy casual 
Some drop rates on items/mats is just ridiculous. For example, Varv Skin. Okay fair enough, easy to kill, fast respawn. Sure Low drop rate should be fine with it, but 0.75%? Really? I don’t have time to grind it to get 15 of em for Beetleback and I can’t grind money to get Varv skins from the trading post either for the same reason! I know, there is a lot of lower cost items that I can get instead but You guys should know, that if You don’t get the goodies you can’t really have fun in this game since every mob will be annoying(Yes, I’m talking about you stupid archer mobs! You can disappear for all I care!)
Since I started talking about drop rates, let’s go over some spawn rates… Glizardons are great examples. it’s like 5 or 6 of em spawning on the whole map and their spawn time is like 5 minutes…(Unless it was changed, then ignore my rambling about it) And there is at least two quests that are connected to them that I know of. So, spawn rate of some mobs is just waaaay too ridiculous.
Bots… Bots everywhere… Well, You will find them in every MMO. Even on the official World of Warcraft servers. You can’t get rid of em completely but there are some ways of restraining them. For example, great idea is to just change the way shout works. Don’t make it world wide, there is no point. Bots and normal players will abuse it to the heart content… It’s like that in every MMO that I played with a world wide chat system or whatever. Change it to region wide for example and it should be fine.
Now lets talk about some boss fight… I know, I know, You can dodge every single attack of the bosses or whatever. I don’t really care if they are dodge able or not. Just make sure that players are not going to get one shooted by a random attack… Thats annoying when you are doing really well on the boss, and then BAM! One random attack hits you and you are 100 to zero in one go. And with that we are going to the next thing…
RESPAWN POINTS! (Just found the shrine at Mge Tower 5f, so my rant about it is a little outdated But still doesn’t change the fact that some respawn points and shrines are terribly placed.)
You died at the very end of the MAGE TOWER 5F? You better prepare Yourself to spend the next 10 minutes on running back there, because the spawn point is ALL THE WAY in the Fedimion Suburbs! But wait! You can just teleport back to the town and use the shrine to get back to the Mage Tower! Right back to the Floor… … ONE! So You will still spend 10 minutes on getting back to the floor 5. Yea, yea, I know, buy the Soul Crystals… But why if I used them up already? Or Maybe I don’t want to waste it while I’m still only level 120 or so? There is just too much running in this game. Wouldn’t be too bad if not for STAMINA which is a totally useless stat, that does not do anything but ANNOY the hell out of people…
Well, there is still TONS of things that are annoying or just terrible, but I’m too tired to write them down for now. BUT remember! Just because I did’t point out a single good point, doesn’t mean that I don’t like the game. I didn’t do that because I’m not here to praise it at the moment. And don’t get me wrong, I love the game. Yea, yea, there been a lot of annoying things happening in the game, but I still enjoyed it and I will still play it. It’s just that there is a LOT of room for improvements to make this game more newb/casual friendly and even hardcore players friendly. Its just not there yet.
I will update this post once I find some more time. Thank You for reading and see you in the world of TOS people! Cheers!
