There are times I really want to dodge, and by all means should be able to without penalty. I just finished an ARAM game with 3 support champions and no ADC. Which in itself, is a guaranteed loss because our entire team literally had no damage. Oh, and they weren't "heal" supports: Sona, Soraka" or "carry" supports either: Bard, Zyra, they were tank supports: Thresh, Leona, and Braum.
Riot, as much as I want to dodge, I don't want to wait 30 minutes either!
