Alliance have 1-4 min queues for all BGs except AV. Minimum queue time is 20-30 mins for AV. Premades are not as frequent because of long queues, but because the best players on ally know that there is a strong movement for organized AV - the best players on Ally are taking the AV queues.
I normally see a lot of former rank 12-14s in AV, meaning we have a competent group that can lead the pugs to victory. This also means that other BGs are lacking ally’s best players and seems we lose more often than before.
