Because of Patch 6.1 introducing new code, HB is down for the time being. As a result, I cannot play several classes effectively, most notable of which is my 660 Blood DK. The rotation on the Blood DK is complex, as is the rune system, and on top of that, it's a tank spec. I sometimes think the very-short queues are not worth all that hassle. Other classes/roles that HB does better than me are Unholy DK (my main's off-spec), BM Hunter (a few buttons sure, but a lot to look out for), and Holy Paladin (**** healing w/o a bot I say). Right now the only two classes that I can play well without HB are the Affliction Warlock (easiest of the 3 specs, though I can manage the other 2 to some degree), and the Shadow Priest (mucking around with one on the PTR). It wasn't always like this, but sometime into Cata I discovered HB and have been using it ever since. In the end, is it pathetic of me that I can't play most classes without HB helping my rotation?
