It's how everyone raided in WoW I'll probably do the same stuff here if for nothing more than meter wankery. This is assuming I even bother with end game.
My argument has plenty of substance mainly, "You are using the exact arguments crappy DPS use to defend their lack of fight knowledge", that's all there is to it. You lost the right to blame someone for being unprepared and needing carried the second you started defending being unprepared. The spell has good utility for a reasonably small cost. It sure seems to beat the hell out of Blood for Blood or Mercy Stroke, but I'm farming both of them out.
If you had a few wipes at 1% yeah you might see that.
