Stop Cho gath's ult targetting minions

So Riot. With a full cooldown when used on minions, Cho's ult is not worth using to gain a feast stack. You even reduced the hp gain from a feast stack and stop the passive stacking on minions beyond 6 stacks. I don't feel it should be targettable on minions with these changes. I'm guessing your thinking if Cho kept the reduced cooldown on minons the other changes would be too much of a buff? Or you don't want people playing passively and stacking feast off of minons?

Garen and Darius ults aren't targettable on minons just so you can waste them with your opponents in a crowd of minions.
