Mordekaiser's W on an ally that is teleporting

Ever Q someone as Master Yi while they teleport away or recall away. You should be right next to them but I guess there is a global range for certain things to take effects. Like I think if you get far away enough from a tower quickly you avoid damage

as much as i love morde I really wish they would do something about his 'w'. he's so immobile hes almost useless unless the team is in your face, even then they can just kite you and kill your teammates leaving you to die alone since you cant run anywhere. I think they should add a movement speed buff to his 'w'

I'm not sure but i think in shields is somekind of range. Even if shields disappear few seconds after teleport, it would be maybe little op if you 4 teammates shield bruiser and bruiser teleports to the enemies.
