^ This. As well as, you know... you're allowed to play the game in whatever language you like by changing your language settings. I'm from NA, but I often play with the text and UI of my game in German and my cutscene audio is Japanese, so... Even if there was a Russian localization and you decided you didn't like it, you wouldn't be obligated to use it.
Although I agree that it comes down to profit margins and I think if support for new languages is going to be added, it will likely be (and probably should be) Spanish first, I'm really surprised people are bothering to argue against someone asking for another language. If you don't want sub prices raised to support the new localization, that's one thing. But arguing against adding a useful function for your fellow players that would give some of them a much more accessible experience is really... :/
