Weird, I guess it's all about who's playing what. Granted I haven't tried solo-tanking HC since week 2, but I was getting stomped back then. Our BrM was able to easily kite, so we just stuck with what worked. We've had a few times where he's been gang-banged by turtles, but only caused a wipe once (thanks to a quick LOH or soulstone). I suppose at these gear levels it'd be pretty trivial to do bats AND boss as a pally, but TBH I enjoy being pretty lazy on that fight.
