Itīs nice that you (when you matchmake as hard-support) find a game within seconds. But itīs very annoying how often you get matchmaked with people of a different language-choice. I choose English as my prefered language but yet get in a full-russian team very often. So maybe just give a choice to search either as fast as possible or tolerate several minutes of waiting until the `perfect` team is found.
To be fair, most of the games the language is correctly, but still here is room for improvement.
