So having just completed a current tier of heroics while it was current (quite a tough one I might add with DA and Lei Shen in there) the advice of some one day week casual raid leader is that I should drop back to lfr? Sounds like retarded advice.
Back on topic, it sounds like you aren't sure where to pitch your raid team. Ex hardcore raider leading casuals one night a week and making them jump through hoops to meet your standards. While standards aren't a bad thing I'm not sure your philosophy is in line with the teams. Having said that, its your team to lead (or destroy in this case)
