I've gone Fury and am getting more comfortable with it, however I do not enjoy it at all unless it's a PURE single target fight like Iron Juggernaut.
No sudden death so you have to wait the entire CS CD to use it. Meaning if you switch to an add and it's not up, you are screwed, or you need to save it for a boss. E.g on spoils HC if you use a CS on the second of the two green box adds then you are stuck without it for a while when the big box boss is open.
Sure, as Fury you put a lot more damage into a CS compared to Arms. But the amount of time that CS is up in Arms compared to fury surely evens the two out.
Terrible AoE. Coming from Arms this is such a downgrade. Whirldwind and raging blow compared to Arms SS + Slam and TC. I went from top dps to bottom on Protectors and from top to mid on Galakras. It also puts me behind on dps on mostly single target fights as well. The rogue in my raid can hit the 1 add on Malkorok, and I can't (for the most part. If only I had sweeping strikes) and on Shamans HC, before we split into 2 groups and have the bosses on their wolfs, I end up pretty far down on the meter just because of all the AoE going on at the start. Sure I can spec Bladestorm and do more at the start, but then I'm losing DR for when the fight becomes single target.
WW x3 and raging blow. Really? And I'm fucked if there's an awkward 2 target fight. Cleave? Brilliant. :/
All Fury has going for it, at least it seems to me, is a much larger opening burst, and a slightly higher sustained dps. Right now it doesn't make sense why most Warriors are fury when Arms is so much easier to maintain a similar, if slightly lower dps, and has much much better AoE.
