@TAdoo87 I found the E50M to be one of the easier mediums. Because of the really good acc you hit a lot more of your shots fired, and the better armor means that you can bully lower tier tanks much better than RU meds. 

Out of curiosity, did you use vents + food or optics and food?  Finding 3 marking shit is easier with optics and food

@Shifty_101st I used vents+food. I don't use optics on any tank besides the Leo 1. I'm personally a fan of dmg farm rather than assist, since you only get tracking or spotting credit.
