The problem is they are doing this before they drop their bombs. I played cat & mouse with one guy until I finally posted this thread.
He'd up out of a base, I'd head that way. As soon as he saw my dot he'd bail and up out of another base.
And this isn't the first time I've gone through this, it happens far to often.
My only point is if people are going to bail as soon as an enemy is near, they should at least have to suffer through the time to get to the ground.
