I’m Russian and I’d love to play on Russian realms but I can’t stand localized interface, quests, spell names and even used fonts. I want everything in game to be in English for me except probably character names as it affects the others. But now I can only turn on English sounds and it isn’t allowed to use English interface on Russian realms. Therefore and also as a programmer I see that localization was implemented wrongly. There should be only one client with multi-language support rather than many clients for each localization. I hope Blizzard will look into it and make it happen some day.
