My guild is kind of a semi-hardcore, learning more towards the casual side, but we do like to clear heroic content. We have only made it just under halfway through the raid on heroic, maybe averaging a boss or two a week during our 9 hours a week, but there is alot of doubt that we'll actually get Garrosh if this far into progression, so few hardcore 10 mans that are far better than us have killed it. Is it really overtuned for 10H, or does it require class stacking? Is the enrage a huge issue? Just looking forward to see what we should work on when we finally get there.
