Riot, please Fix Cho'Gath Q and R

Ok so here is the the problem with Chogath

Q-Rupture- If the enemy is standing on the inside of Rupture, but is on the inner edge, it will not knock up or do damage.

Please look into this Riot

Also

R-Feast-The mark Feast provides Cho Gath to show when you can om nom nom an enemy is awesome, but it does not take into consideration shields. Like Orianna Shield or Face of the Mountain etc...

Please Rito, fix my
