There isn't really soft collision at the moment, it's mainly no collision. BUT, there are some weird circumstances (which I don't know how to reproduce, nor do any of the other developers, so it won't get fixed unless someone works it out) in which it causes you to catapult back repeatedly after running through someone. It may be revive or unstuck related, but we don't know.
Just remove collisions altogether, unlike TF2 where sliding a bit isn't an issue, in empires the slightest slide can result in you or your squad getting slaughtered. Clipping isn't needed.
Didn't a perfect player vs. player soft collision work with no lagging and sliding to the side before? Now I can't walk through a single player without getting horrible rubberbanding. And removing it would just make Empires one step closer to grief heaven. Trust me, I've seen too many players blocking tiny doors and stuff. It's annoying.
I was thinking more along the lines of infantry walking through each other and not the old blocking. I also wasn't aware it was a bug instead of a feature.
