Warrior is the worst class in 1v1, and yes, some classes just kill you with no exp. Im a 2k3 duelist, i know perfectly how to play a warrior, but you have 0 chance in 1v1 against sp, mages and some other classes.
Secondly, if you wanna enjoy a warrior in pvp, it's not like the rest classes. You need to be Arms pvp specced, and you must have a good gear. Good gear means lot's of crit and strength/stamina, which are not very usual right now. It's hard to have a well geared pvp warr behind patch 1.10
There is no need to reach rank10 unless u are going to +rank11, since helmet/shoulders are just fucking crap currently. (Better get Valor one+ lionheart helmet +100hp)
Besides of that, Unstoppable force is not a very good 2h weapon. Dmg and stats are nice, but mace spec is not very ok in pvp imho. Warrior is a good class in open battles, but is the most dependant gear class in the game.
When you have like 5k hp plus lots of ap and 25% crit in battle stance (axe specced is the most succeful) you will enjoy warr, meanwhile random geared mages, sp , rogues , hunters and almost every class will rek you in the most situations.
