Jungle and support needs more attention!
I think jung needs 1 or 2 new masteries and enough points to go with it. cause all jung really has are butcher-feast, and tough skin to bladed armor.maybe a mastery that lets the jung get a moderate increase in earnings when killing monsters that are on the other team's side. This would encourage counter jungling and make it more exciting for jungs.
And I think support really needs to get some type of recognition like "PENTA ASSISST", "TRIPLE WARD", "DOUBLE HEAL". You know some thing to reward supports for stuff they do. That might decrease the chances of being matched with a 5th pick that doesnt want to support. That would save alot of ranked matches from destroying provisionals and kicking people lower in elo. And i know elo hell doesnt exist.Cause being human, every one (no matter the job) want to be praised.
