Use the MMR to your advantage if you don't have them...
Someone had mentioned this in passing in another thread and I took it to heart and I have been getting Achievements left and right now.
With MMR being so goofy and basically broken, now is the time to go after the "Adept X" achievements. I've been making my way through the Survivors and a few of the Killers (damn you Hatch!!! That stupid thing has cost me that achievement multiple times now).
I got adept Dwight and Claudette, I got the T3 Myers achievement, and the Adept Clown so far. I figure I'll just do this until either MMR gets a bit more stable or I run out of achievements to get :D
