The way I see it, creep collision is another "RNG"-like symptom in this game.
Sometimes you walk through the minions when chasing, sometimes you get hung up for 20 minutes and it costs you a kill or you die because of it.
It's random when it happens.
We don't like random.
Why should we like collision?
Conclusion : We shouldn't.
Solution : Remove it.
I know there's going to be some kind of "No!" blowback by the lesser creatures in the community, but that's just the way things should work.
When someone can come up with a reasonable excuse to keep this in the game, then I might need to come up with a more reasonable rebuttal other than "It's stupid."
