long story short, an orc fury warrior in my guild with nef axe/noth axe and some of the best fury dps gear in the game (minus lionheart helm) wants to get dark edge, respec MS, and do better DPS because of it. we have 5 nax bosses down and are working on patch, so you have an idea where were at in terms of raid dps output. the warrior forums on the wow site are utterly unreadable, so id appreciate it if some of you experienced dps warriors could provide my guildie some insight.

Looks like EJ mods are not needed anymore... :P

Edit: And update yer' server list for the profiles. sheesh.

Poor Gurgthock and Kaubel are becoming obsolete.

We can't actually ban them when the time comes.

Also, I completely fail compared to Kaubel's magnificent abilities when it comes to giving people insulting titles.

Not really! Wasn't posting like that more akin to being the fat kid at school? I'm sure the students are allowed to laugh at and cajole the fat kid much more than the person up the front of the room with the big ruler :)

I also said tons of time that 31 arm/15 prot and 5 fury is a much better off tank spec then 31 fury15 prot/5 arm and you can still do ton of dps with a good 2-hander. The difference for horde is much smaller then for alliance though.

2-h gear generally give you more hp too.

MS still got it's use. BT is getting nerfed back to 40% too eventually with MS at +300 for lvl 70, who knows how the balance is gonna be once the expantion hit.

Source? Also, BT is a relatively small portion of fury's dps.

I haven't seen anything saying it is going to be nerfed back to 40% personally. About the % of damage bloodthirst is, I know for myself its around 18% on most boss fights, thats a fairly good chunk imo and losing 5% of that damage would hurt. After this latest rogue patch, I need all the dps I can get to compete with our top geared rogues.

How so? In terms of fury DPS, all you really lose is imp zerker rage and dual wield spec, and imp overpower. Expressed as a percentage of your dps, that number would be in single figures. If you're specced fury/prot, either you "like to play differently" or you're specced entirely for PvE. 31 fury for the best dps, and 15 prot/5 arms for tanking. The loss of TM makes a minimal difference in PvE. You'd definitely still out-dps a 31/5/15 warrior.
Again, generally only useful in PvP. The only reason fury gear is known for giving you low hp is the lack of stam on items suck as titanic leggings / lionheart helm. If I'm pvping or in a situation where I'm likely to take damage (nef P1 for example) I'll toss on helm of endless rage and scaled sand reaver legs. Along with other gear.
Not many people would disagree with MS being better than BT. I've also never seen any post that BT is getting nerfed. Your last clause is the most correct - who knows how balance is going to be when the expansion hits. For now, however..
