Right now both sides take advantage of one particular weakness in the game design. It is a common and effective strategy to fill a sector with enough low level AI defenders to fill all but one or two slots and avoid killing those. This only allows defending players to trickle in one or two players who will always be at a disadvantage. This is such a common tactic that balanced battles with 3+ live players on both sides have become rare. It is frustrating to be stuck in queue trying to reach a battle as your allies get farmed as they single file onto the field. Currently a side's AI defenders hinder defense more than they help it simply because they deny slots to players.
