As has been noted many, many, many times before on this site, rogues and DPS warriors are somewhat unhappy with how tough the level 70 heroics and raids are on melee DPS. Blizz's Tigole has an official response: rather than giving melee DPS extra abilities, they're planning on changing mobs to make them more melee-friendly. For example, he said, Blizzard is planning on changing many 360 degree cleaves to 180 degree cone cleaves, which can be avoided by staying behind the mobs (which is probably where the rogues should be.)
On behalf of rogues, DPS warriors and feral druids, I say yay! What do you think?
