Team Fortest 2

I dont know iF any one plays team fortess here. I was that if would be cool to have Critcal hits in the game similiar to triple damage but also increase the splash damage . All classes could have differant Critcal ablites.
WM could have passive 10% chance that would increase by 5% for every double , muti kill and so on.
AM could have an artifact that would be 100% critcal chance but cost5-10 adren for each monster effect by gun or magic item.
Medic could have something similar to WM but would also effect the people there healing. More chars they heal the higher the critcal chnce is on monster and there teammates.
Engineer could have something similiar to WM and Medics but would only crit while in a turret or vehical.
Obviously the numbers would need to be change because im bad a balancing but this way we could get rid of triple that seems to be at the heart of most balance issues.

Although the triple is too strong, and so lots of things have to be prevented from working with it, I think you will find it very difficult to get rid of it. People like it, and do not want to lose it.

This would actually be pretty simple to do with a mutator, and that's probably the best way to handle it too. Breaking it down so "critical hits" mean different things to different classes just becomes too convoluted.
