I think it adds a lot of flavour to the game world for each race/nation to have its own language so if it can be pulled off in a plausible manner than I'm all for it!
I would, however, urge that people do it tastefully. I've seen a fair few role-players have their character use terms that don't really fit the setting (such as 'senpai') or they're borderline offensive in their implications by using stuff like 'herro'.
One good way to show a character as not being able to speak a language very well is to simply have them struggle to describe something or use the correct word if it's something fairly uncommon that they're addressing.
