It doesn't need any changes. I've used Mida quite extensively since year 1. Something like 17k kills with it. When it comes to crucible, the HCR are really it's biggest selling point. It's 4 precision shots for a kill with it. It's not like people just stand still and let you shoot them in the head, and if they don't move around then they deserve whatever is coming their way. Higher impact scouts are a 3 shot kill. Convalescence Duty, and Last Extremity as two pretty solid examples. There are many counters to the Mida tool. In close range TLW, Monte Carlo, and Doctrine of Passing immediately come to mind, and there are many others. Most of the time if you enter the optimal engagement zone against those weapons with Mida you will lose. Also, a lot depends on whether or not you get the jump on someone. In short I entirely disagree with your opinion. The weapon is over used right now, but lots of weapons are over used. But over use does not indicate over power. Just my two cents.
