I don't think either the Totem of wrath or Bloodlust/heroism nerf will effect people as bad as they think. I ran a couple heroics last night and didn't use bloodlust or totems of wrath. Big suprise not much was different except it took a little longer for the bosses to die. I think that when Wotlk comes out we might not be able to jump directly into heroics. The day i dinged 70 I started doing heroics. I think in the future we are going to have to gear out our toons a little before we jump into "end game" content.
