For the Sejuani mid season update
There was this unintended mechanic with Sejuani and a player created terrain (Anivia wall, J4 ult, Trundle pillar) where she could destroy the structures by dashing through it with her Q. Here is a video how it worked: https://m.youtube.com/watch?v=U8RnGNnTxac As far as I know this is not a thing anymore, but why dont give her a similar mechanic for her update and make it able to destroy walls with her Q (normal walls and player created walls), to add on her unstoppable cavalary fantasy? Just some food for thougth.
