I'm levelling a warrior mainly to use as a PvP toon, but there's a huge shortage of tanks on my server so I'd like to do that as well. I obviously know I'd have to respec for PvP and tanking, but I was wondering if I were in full S2 arena gear and S3 honor gear (what looks like I'll be able to do just grinding honor in S4) would the armor and health make up for a lack of avoidance (e.g. I'd become somewhat of a bear with warrior skills) or would I just fail miserably at tanking?
Note that this is just for heroics and maybe kara...I'm trying to figure out if I'd need 2 sets or if I could make due with 1.
