Ornn Ult vs Yasuo/Braum Shield

Ornn is a stalwart guy..and does mediocre dmg at best, but is primarily tanky and loves to be alone. All a sudden he sees a Yasuo come by and prepare to strike, Ornn ults and a figure of a ram comes at Yasuo from the other end, Yasuo places his shield at my direction and suddenly the ram dissipates before it hits him.

THIS MAKES NO SENSE!!!! I agree that we will be unable to use the pound ult against his shield but it shouldn't shield him from the Ram-charge unless he shield's against that (directioning the shield against the charge, not Ornn). It should hit him, come to me..me hit it then dissipate as the shield would dissipate it then! Yasuo can place the shield anywhere and get a free "no ult from Ornn" button. It's unfair! If he wants to dissipate Ornn's ult he should have to position it against the ram, but free for me to hit him with any of my other abilities as he's vulnerable to me, not the ram.

Please fix this riot!!!! And this goes for any other shields in the game, like Braum!
