I'm well in to revered and I dont think its awful at all. I actually dont mind the stealth stuff, Im glad there is a place in WoW that actually feels dangerous and you have to tread carefully, which is something that the game has been missing for too long. I do agree the ancient mana can be annoying but Ive gotten enough from the shoulder enchant that I havent really had to go out of my way to farm much.
Thing is, once you hit that 8k point there isnt any reason you need to do the Suamar stuff if you hate it that much. You've got the dungeons and 90% of the AP it has to offer.
