1 on 1 I think a Fighter/Warrior would win more often than the Archer/Hunter. Warriors if built right can do massive damage and have a lot of skills and buffs which seriously cut down on how effective an Archer can be.
In all out PvP who can say? If the Archer is attacking a Warrior while the Warrior is busy then it is hardly a fair fight. Same goes for the other way around. In PvP it is down to circumstances and luck.
