Sated devourer interacts with xin's q incorrectly.
I haven't seen mention of it but basically when xin is sated activating your q makes your next TWO attacks deal increased damage and pop up your opponent. I could see why it would be this way because i suppose it might work like an on-hit effect. The problem is, it doesn't stack the extra damage or the cooldown reduction into one of the attacks. So essentially it just gimps the power of your q. You get one less enhanced attack than previously.
There are 2 ways to fix this: Make the 2 attacks still give 3 seconds of cdr on your abilities, or just sever the abilities interaction with sated altogether.
