2 Ideas I think could help balance of the game in the long run.

1. Swap out 15Mpen from Haunting Guise with smaller version of DOT passive from Liandry's torment. Right now its gold efficient Ap,Hp,Mpen item that is often built with Sorc shoes to help snowball in early game with 33 MPen. This change would help DOT champions that do buy it, while also demotivizing assasins to buy it and make them go for Void Staff.

2. Make griveous wounds an active. (Currently all 3 items that offer the passive have no active) This helps drain tanks and healers to not be shut down completely in the laining phase and mid game, while being able to control them lategame. Here is how I thought it could look like:

Unique active: Griveous wounds: Upon activation your basic attacks and abbilities apply Griveous wounds to the target reducing their healing by 80% for the next 6 seconds.(30-45s cooldown)

Ok, ty for reading, bye! :3
