I mean making the animations bland obviously isn't gonna be taken well. The old W and R both had way more flair to them than just a bubble and an orange cone. Just like Blackbelt Udyr now having the bear stance model while in tiger and turtle (which hopefully is a bug ?).
I think people have nothing against small visual effect updates just that "dumbing down" animations and removing what makes them unique on a champ that already doesn't have much going on doesn't seem great.
The blackbelt udyr is a bug, yes.
I'll simply disagree that they are more "bland", but you are free to believe that.
