Stupid but what's the point of the translation? You still have to write English in the forum and saloon chat. You don't know who you're writing to. Whether Adventure Event World or International Fortress Fight World Cup. The Saloon Chat there is no translator and forum
Sure, but with IFBC you're with your language's team. Unless some very specific design wins, where you'll have to cooperate fully with other teams, you only really need to talk within your own party. In a language you already know. So the translations will just make it easier to get around in the game - sure, mostly everything will be designed the same way as before, but for some people, older people from smaller countries perhaps, English is challenging. Imagine if we were suddenly forced to play on a Chinese server, arabic server. If you don't know a language, the alphabet doesn't matter that much, a little simile for you.
If, for some reason, we will be forced to interact with other teams, the monolingual people can still rely on the multilingual people in their teams.
It just makes the game easier. Not all functions are meant for all of us, but please learn to appreciate it for those who need it. This is a good tip for real life as well, as not all of us need pre-cut fruits, wheelchair ramps or extra large letters on signs.
