I heard some disturbing allegations about the post patch mobile AA

Allegedly the variant of its cannon that is a very slow firing dual autocannon that is already hard to aim at up close, has its damage vs infantry  reduced so that it dropped from a 2 shots kill to 5 shots kill, without any patch notes about it.

Why on earth would one do this to what is already the worst ground vehicle in the game? All this does is to give even fewer reasons to anyone using that thing to ever leave the safety of the spawn zone from where all one can do is spam AA missiles at.

What the heck DICE? This is the patch where you are supposed to address how bad ground vehicles were, not to make the worst one even worse.
