[Gameplay] Part of Revitalize does NOT work on Mordekaiser (With detailed experiment result)

Hi guys I'm a Mordekaiser main :) The following experiment for revitalize is based on the shield part

Here is the experiment I have conducted: Condition: Same rune except for presence/ absence of revitalize (Domination + Resolve) , Mordekaiser lv 18 with only, charging shield with rank 5 E to one enemy dummy > With Revitalize: > >40% hp : 130 -> 301 ; <40% hp : 130 -> 301 > Without Revitalize: >>40% hp : 130 -> 293 ; <40% hp : 130 -> 293 > There is NO increase in shield for <40% hp!!!!! I've also tested for the healing part and it turns out right Increase in healing with revitalize and the healing further increases if Mordekaiser is <40% hp

Here is the summary of bugs discovered:

First problem: The 10% increase in shield for <40% hp for Mordekaiser is bugged (not sure if other champions have same problem)

Second problem: The increase in shield value NEVER show in Rune column in game but the healing part is shown normally

Last problem: Casting and W2 at the same time will cause visual bug of W for the rest of the game (W visual cannot be seen for all players in game including Mordekaiser himself). I've reported this here patches ago but seems no one respond.** It is 100% reproducable!!**
