I know when to use LB, thanks

I was doing Moogle yesterday with two whms. Players were dying here and there and our mp was quite low so I said ballad to the brd and then a minute later said ballad again. I guess he took offense and said "Don't tell me how to play. You guys aren't suppose to be dying". Next thing he did was /sit during the next round and we wiped. Then hes goes "HAHAHA did you die because you have no ballad?" For some reason players just can't handle being told what to do even if it's correct.
