NOED is bad... For killers
Just think about it. MMR is balancing your games so you get 50% killrate. Whatever you bring in your games, whatever perks you use, this will be true. So, if you are struggling in your games and don't get any kills - you will get lower MMR and more chill games. However, if you are struggling in your games, but cheese some kills in the end through your perk - your MMR won't get lower. The matchmaking thinks you just had an easy victory, and gives you even more skilled opponents in your next game. And then you have to cheese your kills again. It is a self-sustaining cycle.
Just a thought I wanted to share. I just realized this and dropped NOED from all my builds.
