Bans for Leaving

I understand LeaverBuster and other mechanics and their intended purposes, but it is a little broken in two major ways:

1. You can't see your ping before a match starts
2. You can't queue dodge without punishment.

This is problematic in a few major ways:

1. If you enter a game with 500+ ping, you are basically useless to your team, and almost can't help but to feed.
2. If you go into solo blind pick and your team can't decide on a composition, the best option for EVERYONE involved is to dodge. It prevents your team from entering a game that they are going to lose.
3. If two ADCs get insta-locked, your team is screwed. See point #2.

As a result, people are penalized for being HELPFUL to their team and the community in general. Now, there are some asshole dodgers, so I don't know how this problem can be properly resolved, but there is almost certainly a way that it can be done.
