That's an argument for nerfing the Cromwell's crush, not removing crush altogether. Removing crush seems likely to have a bundle of dumb knock on effects, especially at high level play. If I pop hit the dirt behind a PIV, is that PIV now stuck? What if there's a suppressed or pinned squad behind it? Are you cool with losing it in those situations?
Besides crush was actually one of the best balanced things in the game. There was a neat risk/reward curve-you can get a squad, but because your positioning is predictable you can easily be baited into mines/at guns, never mind the snares.
You cant nerf crush without nerfing cromwell\M10\T34 mobility. Crush happens because of really fast turning speed. Sure if you want to nerf crushing for thouse allied tanks, you have to nerf their rotating speed, which is nerf in general, because all thouse tanks based on mobility.
I'm not fine with that, but I dont rely fully on crushing, its not main tanks AI, and I wont miss it so much, because crushing for axis is already situational. Crushing as allies is regular thing, no matter what.
But ok, if ppl want to trade mobility of T34\Cromwell\M10 but keep crushing in the game (and it would be same situational feature, which would appear in 1 out of 10 games) then ok, let it be.
