No, they are not. Now maybe 4 or 5.. I can't confirm that. I can confirm 3 rogues can beat 3 warriors.

Yes I would if he can tank for me. His job is to block (like the offensive line in football). He doesn't have to heal me, I'm a sorcerer and can heal myself (and the whole party for that matter). Warrior's job is to tank and keep the opposing bad guys away from me while I use my range skills.
That is actually the biggest factor in determining how well I do in PvP. If I have a warrior who can tank then I get loads of kills. Without that I get mobbed and die very fast.
