Gun goddess MF ruined it all
The trend was going so well,

Jungle ulti skin - Udyr
Support ulti skin - Sona
Mid ulti skin - Lux
Top ulti sk-wait, what the fuck? - MF

The issue is with the outdated thinking of locking a champion to a specific lane, i have seen Udyr top hundred more times than jungle, i have seen Ezreal in all lanes, i have seen Lux more times bot than mid, even the AI Lux almost always goes bot and i have also seen Miss Fortune top and mid a lot of times. All of these champions can go to multiple positions and apart from this there was never a schedule that locked ultimate skins to a specific class based on random player opinions on where a champion must go.
