"Are there any other exploits that could be used in comp that still haven't been fixed?"
The switch speed exploit has only recently popped up (on Delfy's Channel https://www.youtube.com/watch?v=b03UXBTcQaQ), before the videos release it was known by only a small community (who didnt use it maliciously) and from what I'm aware it's not patched or blocked by any serveme plugin. I don't think many competitive players know about this, I think I've seen it used in other leagues, this is not relevant to Odin, just thought people who don't already know, should know about the existance of this.
for those who also dont know, this is an example of max lerp (sent to me by a friend who does not play competitive)
