@Riot Change the passive on Morde's e

I played Mordekasier for the first time ever in facr, as a bot lane ADC and you know what, I had so much fun, it felt different but in a fresh way so overall this is a positive post about the reworked morde rather than a negative one.

There is one thing however, I do find cheap and tacky, the passive on his e, where he does not share experience each time he gets a kill, it leaves a rough taste in the mouth to have a part of his power budget spent on a passive which he loses the moment he hits level 18 and this is made worse by the fact that he is supposed to replace champions specifically designed to scale into late game, so I was wondering if it would be considered to keep his kit how it is, but remove this passive to slightly nerf his already strong early game and give some much needed power to his endgame.

For example a new passive could be added to his ultimate where he gains a small permanent stat bonus each time he enslaves an enemies' soul, maybe base this bonus on the stats of the enemy he enslaved to still maintain some element of playing a farming game in botlane, or a permanent bonus to the size of his shield. I don't think this damages his identity as predominately a replacement to the ADC and it does make mid and top lane Mordekasier viable

Thoughts?
