Some changes I thought of:
First thing:
The icon which hovers over Sej is more than enough for clarity imo so I think the vfx on Bristle can and should be removed.
Second thing are her two oldest skins. (Sabretusk and Darkrider)
Both cost 975 and don't change much while at the same time there are 2 750 skins (Beast Hunter and Dankelf (forgot its name lol)) which actually change more (they both have unique R missiles)
How can this be?
I have some improvements which could make those 2 skins have a better quality.
Sabretusk:
Try mud vfx instead of snow and ice. Just change the colour and that's it. Mud can become pretty hard so the ice would also not be a problem.
Darkrider:
I always imagined this skin to be a by dark ice corrupted Sejuani, just like Blackfrost Anivia. So why not make her ice abilities to dark ice? Again, just a colour change.
Third thing is her Bear Cavalry skin.
I rly like the commie star as passive icon over her.
My problem are her SFX though. Her best sfx are just missing. (her old W windup and her old E proc)
I have some ideas where to put them:
put the windup sound from her old W on the slow area of her R. Cuz the storm is kinda charging up anyways.
And the E proc could remain on her E, more specifically on her Icebreaker passive. So if the ice is broken by Sejuani it plays her old E proc sfx and instead of this weird orange ice you could use her old E vfx but bigger or brighter.
