infinitely scaling AP gain mastery for supports?
I see a lot of complains about supports lacking good AP items.
Perhaps this problem can be solved by giving the support tree a mastery that gives a permanent AP boost every time an ally kills a nearby lane minion/monster/enemy champion? (kinda like the gold gain mastery)
You can prevent mid-lanes from taking it by rooting it deep into the support tree and maybe disabling it for a few seconds if you kill a minion yourself.
Depending on the ratio of gained AP supports either don't have to worry about AP builds or can make up for the lackluster AP on support items.
I hope it's not a crazy OP idea, good luck with it.
