if you are the 'only' 'pre-made' group in a BG you are also the leader in that battleground

often when queueing in with my 5 shammy's im the leader, yet still most are scattered around groups
but you got the power to change the orders and regroup them into yours


ONLY reason for you NOT to be leader, is if someone else using 'join as party' got in before you did...
90% of the time they are a 'premade' group too.. and will usually respond well if you ask them to regroup you
