Leave forgiven...

I think under "honors" you should be able to forgive an allies leave for any reason you deem fit. This should require TWO honors but premade teammates should only count as 1 regardless of how many of them forgive you. Sometimes leaves are understandable via power outages, emergencies, or even you're being harassed by another teammate so badly that your team is understanding (even if I personally don't agree with it).

Regardless of the situation if your own team sees fit to let you off the hook they should be able to but ONLY if they see fit to. Even if it's used in 1/100 matches it's 1 step closer to a more friendly league environment no matter how small.
