I was thinking of giving it a try and I wanted to hear everyones opinion on it. What's it like?

What would be a good class for me if I want to primarily buff and support but still hold my own in melee?

There are no roles (tank, DPS, healer, etc.) first of all.
If you want to buff/support I'd suggest Eve Code Nemesis as her buff is AoE but very hard to play and not flashy at all. Code Empress will be more fun.

However, currently, Elsword, Raven, Chung are OP as fuck, especially Elsword. Do not PvP until you are level 40+ and have a very solid foundation of combos and control of character.

All in all, fun game but casual, so not something that you would play like WoW for hours and hours.
