Sejuani idea

So hello .. I was wondering how riot said that is first champ/rider who has mechanics cuz of he is rider .. that they can made without bristle and it will not change (funny see artic assault without him) .. so I thouhgt and drawed a little sketches how she can have some mechanics too .. (btw i dont know hot to upload image here) ... so _She will be normal like she is now when on Bristle _When she die she can grow cuz of his death (mechanical like aatrox passive) and then continue with low hp without him or something like that _when ult disabled she will get some new abilites ..

Q... still same but with shield (yeah I miss him) she can do something like arctic assault or slower or shorter

W... she can on short distance grab someone with her weapon and then trow him back with shield (lovely meele battle and great combo with Q.. while both skill shots)

E... still same .. or something like "memory of Brislte" so she can ride a little distance on his ghost and get for like 20s old abilites

R... disabled on ghost too

so then so then is tactical question on team .. sacrifice sejuani (after her dead they will respawn together with Bristle) .. or go to team fight without Bristle ?
