While most games have different attributes like Strength, Dex, Int, Constitution in a D&D system this game has nothing, all 19 class are the same ****. While most games have different skills that escaletes with Dex, HP, Evasion, Intelligence, all skills escales with AP, so the only way to go is AP. While most games have you need to choose skills to have, you need to create a "skill build", here you just need to "buy" it all e lock what is too bad designed to use. Without AP you don't play even PVE, if you do a tanky build you will grind in Rhutums. AP is the only things that works in this game. The game design, like most already said, it's the laziest **** ever made in MMORPG, and there is no possible solution unless skills using different stats to do damage while others don't, so you choose a different set of skills for each build.
