I'd personally love it if we had more 5man content incoming with new patches, say 4-5 dungeons per a content patch. the current only 9 heroic dungeons are getting old.. fast. aswell, i wouldnt mind a third difficulty for heroics, making them even more harded, with 1-2 itemlevels higher loot, as i for instant think that heroics on their current status can be steamrolled almost just as they were in wotlk. they're not hard, in any way. - please notice that this is not a qq post to up the heroic difficulty, just a post that us, who genuinely love 5man content, would be able to get into real challenges., i also think that there shouldnt be any sort of achievements other than a possible feat of strenght for completing these superhard heroics. (similiar to starcraft 2, hard > brutal difficulty differences, though i'd love if the difficulty would be bigger in comparison to earlier mentioned ><)
ps. forgive my grammar, tired and english ain't my first language.
