Expioting means to over-use to get the greatest possible adv over something. MLG has it's own rules, but on matchmaking at times it can be very cheap. But once or twice in a session can be alright. Also with lag it gets interupted plenty of times. But I do see where you are coming from. In theory, if u jst wait for the melee to finish and then Fire then it is only BRing. ;-)
