Neh don't go fury. Arms will perform a whole lot better due to ice tombs. I've been rank 1 for quite some time on Hagara as (SMF) fury but I'd be rank 130 or so if you compared me to arms warriors.
It's really pity a fury warr appears to be severely crippled compared to arms in 4.3.
That was not so obvious on normals, but with HC progression, I find my warr in the lower part of dps charts for most fights.
Ok, it's only 3 for me, but WoL tells the same - arms simply outperform fury on _all_ the HC fights by big margin.
Looks like only a matter of time when my RL will tell me to spec into arms, which I don't like at all.
