The short answer in nope, the long answer is noooooooooooooooope.
you can't go fury in rbgs, so you're left with either learning arms or learning how to FC
you can tank 5 mans just fine in a pvp prot spec by the way, so i believe this is the route you should take
also, learning arms might be challenging, but it's a great spec to have fun in bgs with so make sure you try it later
Just go to arms.
EVERY good RBG group needs/wants a prot warrior. No good RBG group needs/wants a dps warrior. Plus fury is a big step down from arms, and arms isn't even very good.
HOWEVER - if your guild plays below 1500 MMR and is just playing socially sure why not be fury in RBGS? It's just for fun after all. You won't be helping your team but < 1500mmr you probably won't ever get purged and you will get to do some damage every few minutes .
Arms is shitastic and Fury is even worse than Arms. Fury for RBG is folly as fuck broski. Spec Prot instead, it's WAY more fun.
Hail Thor-show thy might. Let thunder roar and lightning strike!
Hurl thy hammer into the fray. And let thine enemies know fear this day!
VICTORY, OR VALHALLA!!!
