Reply 1# 76.*.*.124 (tried to sort everything in recommend order (higher = better) :P
Balanced
TaoEast - A bit to much skills for a start but most OP class for no so it's easy to pve pvp.
Berserker - Huge dmg, easy to combo in pvp, lot of people like his splashy skills. :D
Warrior - not so much on skills good AoE for pvp, big dmg.
Illusionst - defensive style of play throws lot of random thingys on screen. Not relay a recommend for new player but it won't be the worst choice :D.
PVE
Elementalist (blue stance) - maybe easiest class for PVE :)
Ranger - a bit hard with monsters but relay easy on boses
Warden - Not a best choice but she have few summons and freezes a lot.
PVP
Scout - if your a bit his traps make pretty big dmg.
Guard - better to start because he have lot of hp so you can survive a bit longer XD. But low dmg so will be pretty hard to kill someone xD.
Forbidden
Assassin - Need lot of practice and precis control
Slayer - shes pretty much a assassin in skirt :) but a bit easier to handle :P
