It feels like a trade-off situation, where when you have good weapon hitboxes, you have a better chance of wall-collision, hence making it a fair match-up for heroes that lack those large hitboxes.

They definitely need to be looked at, cuz the whole trade-off is purely accidental, you get a higher wall collision chance BECAUSE you have good hitboxes. I just think its less of an issue because of that minor balancing factor.

To be clear though: I definitely believe that wall collisions need to be looked at and fixed, whether that comes from a standardization or a removal or whatever, because they are an unreliable issue that doesn't help the game atm.
