The problem comes completely from the little bird. I never even see assault helos anymore, they just die in .2 seconds after taking off. Transports die way too fast too, even though they are supposed to have some damage resistance because they are a TRANSPORT not a combat helo.
The little bird just dominates everything. It dominates air, it dominates armor, it dominates infantry, it dominates water, everything. The thing is completely unbalanced, and we are only just now going to see a nerf to the thing even though it's been broken since it was added.
