I should have taken SS but I guess you'll have to take my word for it or ask my guildies who I do 5mans with =P.
Last night was the only 2nd time I respec to DPS a heroic. We did a bunch but here's the 2 heroics that I think shows how TG warriors "don't suck" at 5mans.
Heroic Caverns of Time
A guildy was asking for DPS for H CoT. I volunteered. At first he was reluctant but I told him that Fury DPS warriors own.
Ok, the thing was I haven't DPS H CoT as Fury ... only as MS which I did ok. Now I'm thinking "Oh crap now i gotta deliver! hopefully I don't suck".
I was averaging 4000-4400 DPS on bosses.
On the 2nd boss somehow I managed to pull 4890 dps ... The extra adds with low health helped me kept Victory Rush up. Was that cheating? Hell no, it's part of the game mechanics just like mage/lock AOE.
And of course we got the Bronze drake for our drood tank.
Heroic Violet Hold
We 4manned this instance because our rogue didn't get in time when the door closed. I was averaging 4400-4600 dps on bosses. Not bad at all.
Tonight is 25man Naxx and I'm really excited how will I do on Patchwerk, Thaddius and Loatheb. Last week I pulled 3600 DPS on patchwerk as MS warrior.
So before you say "lol what? No we don't need a dps warrior" or something to that effect think again.
