Regarding Mordekaiser's recall
So, with yesterday's PBE update Riot changed the animations of Morde's recall.
Instead of using his Attack(2) frame into his laugh his new recall consists of just Idle3->Laugh->Idle1
I personally liked the horizontal swing but I felt it could be improved to make it look smoother.
The change I propose is Attack2->Laugh->Idle 3 Effectively making him swing his mace, laugh and readjust it on his shoulder, making his recall be based around him just displaying Nightfall.
Just my two cents though.
