the pattern of cracking shields and always having confidence to push is a stupider pattern of play.

That really isn't true though? Evan cracks shields constantly and doesn't push because it's not the smart thing to do. There are way more variables to consider in pro lobbies than just doing damage and pushing.

Plus you said before that roller brain is just getting in close range, but by that point they've already committed to pushing as a team so it really has nothing to do with roller brain it's just a coordinated team play.

the aim assist is warping their confidence because they are 40% less likely to be affected by panic (0.4 aa). That's a pretty huge mental advantage.

If roller was "mnk + 40% aimbot" then that would be true but it isn't. Roller is harder to use manually than mnk. Don't really care to get into the AA debate just wanted to point out the comparison is flawed.
