For newcomers: The levelling system is too confusing and boring.
For regulars: There is nothing more to do.
I voiced out my concerns about the game here and the issues faced by newcomers. I managed to get some friends playing but I can imagine if they had no guidance they would have gotten bored and quit (which would probably be better for them).
All the low level areas are useless, the game completely skips over the fun of the levelling system. Even now whenever I create a new character, the levelling part is a chore. I can get through it and reach 300+ within a day doing quests. But there’s entirely no fun in that. Maps are too big and confusing, spawns are so sparse that you can even have a lack of mobs for quests much less for grinding. Mobs have no character and no cohesive theme. The most ridiculous thing I have found from day 1 is that it’s actually difficult to play and level as a party. As long as you’re not on the same quest somebody has to literally wait around. And quest objects picked up by party members don’t count if you’re too far, even on the same map. And warps sometimes don’t affect all party members, everyone is fighting their own boss instance. In addition to the countless bugs to the quests, non-linear maps, and obsolete low-level maps, I’ve had so many people ask me they had no idea where they were supposed to go or do at low levels.
The problems with the endgame, most people have mentioned their concerns. Dungeons and Raids have always felt like a chore to me because the runs simply weren’t that fun. A big reason is because most of the mobs and bosses in ToS are stupid. Most mobs are so slow they will never hit you, and their hits don’t mean anything anyway. Most bosses are HP sponges. Skiaclipse was the most fun I had with a boss in a while but then nobody bothers with the gimmicks like the side rooms anyway.
Everybody is aiming for the same armor in the end, and hope to get the most stats from them. There’s no unique weapon or armor that can be hunted from mobs that could work in a niche build or something. The diversity is slightly better for weapons, but I dislike the forced synergy that most of the effects have.
Class balance is quite messy and as before, imo forced synergy between skills is just a bandaid in making certain class combinations more viable. There isn’t enough diversity within classes for what they can do imo, they usually have a good skill and a bunch of crap skills so there’s no alternate build for it. Many skills and buffs are just clunky to use. Some classes have no identity or can’t even perform their supposed role well. And for most of the content those roles aren’t required anyway, 1 healer+4 dps is optimal for most pve content. Good thing is that scouts seem to be the most diverse but there are a ton of old classes which sorely need updating (esp from Cleric and Archer trees: Paladin, Hunter, Krivis, QS, Sadhu, Monk)
So after you’ve created a few chars and levelled them, all the game consists of is doing daily dungeons and CM. Pop a raid or two. There’s no grinding (except everyone farming HG), no exploration, no worthwhile sidequests. Even farming for a few hair accessories was kind of interesting but none of the newer mobs have unique drops anymore. Everything can be done solo, and in the case of levelling and CM, even better done solo. And when there is no change for months, your token runs out (if you had) and you just take it as a sign to stop for awhile. And pop your head in once in a while when something new is introduced and get put off by all the chores you have to do to get back up to date.
