Nerf 2 Hextech synergy
For how easy you can slip in 2 Hextech units, their 2 unit synergy is way too strong. (With Jayce + Camille early and Vi + Jinx late) Now, it’s pretty impossible to win as Rangers or Gunslingers (both require items on units to do anything). As you will always be just completely stomped by this easy to achieve synergy.
Maybe tune it back to the previous version where the 2 unit version lasted 3 seconds, and the 4 unit lasted 7. This will help make it less oppressive, and will add value to those trying to go for 4 Hextech (Which you should pretty much never do right now)
