Morde R "fizzles" almost every skill in the game
The champion I'm noticing it the most on is 
If you rupture during, before, or any time in the century of morde's ult cast, and he takes you inside his realm, your Q just doesn't do anything. Same with Sion's Q which really makes no sense, I could understand Cho Q being a "ground" thing, targetting the "normal" ground and you're both taken to "shadow" ground, but why would Sion's Q channel be fizzled by morde ult. He ults me, but my spell doesn't hit him? Real work needed to be done on this before it was released, this stuff is too bogus.
