Hey Raiders,
First, don't take it personally. Seriously. Maybe the temporary vote ban was warranted and maybe it wasn't. No one else has chimed in to give a different perspective so its hard to tell.
On this map the AA can make or break the game. It can lead to a teams easy win or a frustrating demise.
It's important enough that a few people have made guides about how to properly use the AA.
Here is of those guides:

If you are serious about using AA when playing, Id suggest reading and learning from it. There are also other posts in the tips and tricks section. There is a lot of great material in there to help make you a better player.
Make sure your communicating with your squad and well as paying attention to the team chat. You'll get instant feedback there. Good luck.
