Are there only Russians here?

Yeah well, maybe you haven't noticed but English is an international language that is more or less known everywhere, whereas Russian isn't. Also it should be pointed out that Russian uses different alphabet, what makes it even more "exotic". The fact that you don't like English is meaningless, as it is an international language, used by organizations to contact. So learning language, with its very different alphabet, sufficiently to understand what the campaign heroes will say is rather impossible, one would need few months, even years to do it. The international community is here neglected, even by officials, which is quite bad and demoralizing. Not to mention the Akella's bad organization, it aspires to be a worldwide known publisher but at the same time makes such horrible mistakes as not providing a publisher for one of its most known games.

I wonder if Diablo 3 or Starcraft 2 (or any other game you would die to get) would be only in Japanese you would also say: Learn it or wait, without any complains, just taking it for granted.
