I find it strange they, in my experience, locked the motion blur strength cvar, but didn't lock motion blur. Using transparent viewmodels on your HUD requires you to enable motion blur, but you can set the strength to 0 so it doesn't really do anything. But in MM it's one or the other.
Also there needs to be an accept button or something (in addition to being able to choose a region/acceptable ping). I blocked southwest NA/EU/SA servers in CS:GO because I consistently got higher than 120 ping to southwest NA, and since I was blocking those servers already I might as well block all the others around the world. This caused me to abandon a few matches before I remembered I had regions blocked for CS:GO MM.
