Good points. I do however never want to see it with suppression on the move again. Too op for my likes.
It could do, perhaps, with a sort more profound anti air role. Like the Schwere hq has, where you put it to anti air, which makes it as good as its current superb anti air. When this mode is not activated, it can have improved anti infantry performance. Perhaps more damage?
Well that would still make it extremely situational to a point where I can't imagine anyone would pick it. Perhaps a vet1 skill where it could "hunker down" for a timed period which would significantly increase damage and suppression, but the ability would be cancelled as soon as it moved?
