Fellow KV-2 bro, allow me to clarify.
I was not claiming vehicle prioritization was around since the beginning. I was claiming not having access to abilities while garrisoned has.
Were incendiary rounds not there? What about volley fire?
It doesn't really matter anyways because "it was like that before" would not make the argument any more valid.
The only question that really matters is: Does it make sense for the rakketen to lose its vehicle prioritization when garrisoned? The answer is a resounding NO, even if the window of usefulness is very small.
