i've read thousands and thousands of diffrent opinions on warriors, but i would like to ask you folks here what u think about them.
How good are they in 1v1? Do they have a lot of bad matchups? Is warrior worth investing time in or will i go nuts everytime i'll have to kill a caster/ranged charachter? What about 2s and world pvp?
For the other part, i've heard fury warriors are beasts in pve? Is that true?
This^ If you want to duel outside Orgrimmar, then you're looking at the wrong class.
In wpvp - a warrior can deal huge amounts of damage before your opponent reacts, but if he is aware of you you'll most likely die.
In 2s - just grab a Hpala and enjoy ez rating. Unless if you're against SP + mage. Then just leave the arena and dodge.
In PvE - Fury is the most gear-dependent spec in the entire game but therefor it is also the one with the highest numbers once it gets there. Nothing can beat a Smourne + Gloren BiS Fury's DPS. Warriors overscaling in high-end PvE is a mistake Blizzard had admitted many times. Only TTW mages and Combat rogues come close.
Every class has its challenge, you master your class when you can beat your counters, if you can do that with a warrior you are undefeatable, but its frustrating in 1v1 but its still fun.
