Honestly, IF Stormraider's Surge gets removed Morde's VGU should better be lurking the corner
As of now Runes reforged seems to be getting rid of a lot of Keystones and the recent poll on which Keystone to keep Thunderlords got chosen, which makes me pretty upset, not gonna lie.
Mordekaiser currently performs really well since Stomraider's allows him to stick to enemies and get his 3 Q's off, if he loses that reliability he'll be a lot worse than he is now and would rely 100% on his allies to even get his damage off.
I'm just hoping that either: A) Mordekaiser is gonna be the next VGU after Urgot and Eve B) Stormraider's gonna stay C) There's gonna be a suitable replacement for it
and smash

. Most Nunu's I see take Stoneborne Pact (If they're jungling that is). Remove that, Nunu might fall off the face of Runeterra.
