Mortal Reminder

This item seems problematic for and specifically. Both of their kits revolve around the use of their healing to out sustain and also surprise opponents.

WE have , which also has Grievous wounds. However, the grievous wounds on this item doesn't kick in until the enemy is below 40% hp. Im not so great at math, but I noticed grievous wounds is also being lowered from 50% to 40%. However, I still think that by allowing any champion with Mortal Reminder to apply it from 100% hp, we are seeing quite a nerf to these champions.

Will they be compensated or reworked...?

I play both of these guys and while strong, they both have their exploitable weaknesses. as it currently stands, one can play around Grievous wounds; it's a challenge you have to accept when playing these guys. Some options are there for dealing with their healing, and that's great. Im not opposed to AD users also having this option, but having it applied when the enemy is at any level of health is a bit much.
