1: It certainly isn’t very party friendly, but the exp benefit of a party working together to slaughter mobs, or the exp bonus from party members in dungeons makes it extremely worthwhile when you get high enough level.
2: The game has an inherent difficulty that goes up, mostly based on your build/class some have harder times early on some always have a difficult time. Sure I slaughter typical mobs, but field bosses/dungeons are a completely different story, even if you are the same level with a field boss it will most likely slaughter you and you will rub it’s stomach with a feather.
3: Define grind fest, because all mmos have an good amount of grind. The max level currently is 280 much more than the typical mmo. The FINAL max when everything is in is supposed to be around 600 so… grind? Yes. I mean a few hours a day and you will get a lot of levels anyways.
4: The game isn’t an ARPG if you think that sorry it’s a typical mmo like Ragnarok was. Sure the combat controls are really intuitive and puts you in control of the combat pretty well, but guild v guild wars will be a thing when people get high enough to make a guild that is… On top of the fact there are Raids, and yes you will want to farm for good gear, there is pvp and things like that.
To also note. There are a few really hardcore players that are in the 100’s and it’s only been out a few days. So there is that.
