I've never ran into a Russian person on Counter Strike before, but I have had a few Japanese people. Luckily they knew English (for the most part). I feel sorry for you though, I always loose when my teammates have terrible communication.
Yeah, it's really easy to carry your team when there's 2-3 russians pre-made rushing out dying one by one. On DD2 T-side, all 3 of them decided to rush through the little tunnel at mid, and they all got killed cuz they lined up to an awp. How am I suppose to adapt to that teamplay? It's plain out stupid. This was a game in MG2-MGE level, and it's too much too ask for someone to clutch a 2v5 every round. And to top it all of, they decided to use their microphone as a music player, so I had to mute them all. All the russians I meet in MM don't say much except: "Cyka blyat, idi nahui" anyway, soo..
