One free dodge per patch.
If your client crashes or you get a team you know you'll lose with, why are you being punished for it? It's frustrating, particularly when you're forced to dodge two in a row and lose 13 LP total because of it.
I understand that dodging holds up the other nine players, however dodging is also absolutely necessary on occasions.
All players should be given one free dodge per patch starting at level 20. This is just one dodge that'll be used up if you use it in any matchmaking mode, and you may only hold on to one dodge.
