Kind of curious - how much does scatter play into tank v tank combat (opposed to accuracy). I always thought that scatter was more for AI purposes and the KT had it's scatter increased because it tended to frontally solo AT guns. For that reason I'm not sure how much the scatter plays into the KT now generally being UP (compared to Jackson buff or what have you).
On most tanks scatter is low enough so that most shots that don't score a natural "hit" scatter into the tank hitbox and potentially deal their damage. But when the scatter value becomes high enough you see shells flying past their targets more frequently. Scatter is mainly intended as AI because either 1. model size is low enough that scoring a natural "hit" against individual models almost never occurs or 2. accuracy is never even considered when a tank fires a shell at infantry. I'm unsure of which CoH2 uses, but I'd bet its one of those.
The problem is that scatter is an exponential value that gets incredibley worse the higher it goes. At least that's my understanding, I may need another lesson on it though from Mr. Smith
In conclusion: Scatter plays more into tank engagements the higher the scatter value is (and lower the accuracy is, plus things like target size etc), hence why the KT, IS2, cromwell and comet can be considered more "RNG" cannons.
