The casters fight from a distace while the warriors fight up close. Like in PVP its easier to get gained up on as a warrior.

I keep getting killed easialy in bgs and i am also wondering what i shoud use for it fury or arms and some advice for warrior in bgs would be helpful.

The warrior is a harder class to play, although in BGs they arent bad at all. You got a lot of stuff to stop incoming damage, shield wall, spell reflect etc. and beserk and such to pop out of snares. Fury right now is OP due to the massive ammounts of damage they do.

not at all. i actually find wars easy to play. all around.but it deepens on how your hot keys are set up. your key blindings and your level.. they got all types of moves to help you in a bg also like hamstring and ofcourse charge. and if ur 69+ arms blade storm is amazing specially for when more then one person is trying to cap a flag or somthing.but wars are pretty good so just play him a bit level him up a bitch set your hot keys and key blindings well.. use your talents right. make sure you got top gear if u can for ur lvl.
