bards shrine never see's full potential outside of laning phase

it's real handy when your in lane and you can easily let their power charge over 10 seconds under your turret but 15-20 minutes in to the game it's pretty much strictly used for the instant heal, which is only 30 / 60 / 90 / 120 / 150+20% ap, pretty darn weak.

I'd say the initial heal should be 30 / 62.5 / 95 / 127.5 / 160+30%(if not at least 25%) ap, that increases up to 230+45% ap over 10 seconds of charging.

this would keep it's charge up power in check for laning phase and make it a fair instant heal mid-late game
