It seems pretty silly to me to vote against a language learning function just because it's been giving you a
technical advantage ingame. Just think about situations in the "real" world. There are probably PLENTY of people in your life who you preferred didn't speak, let's say, English. Just so you could talk about them behind their back...... to their face
. Now think about it. I've seen plenty of people pretend to be ignorant in a language before in order to hear things said by other people who don't know the truth.
Yoo-hooo!! This is
easily turned over to the RP world. You can play a character who interacts in only his native tongue by day, and then feverishly spends his nights studying the language of another race. Though I think it should be an extremely, extremely slow skill to acquire (a miniscule boost according to intelligence, perhaps), I'd say this should be implemented, should the opportunity arise to do so. Right now, it's as if we're taking advantage of it like some sort of private player-to-player paging function, like those used on Tibia.
As a personal example, I rode a German airline on the way home from Europe this past summer. I was kind of disappointed that my aisle buddies were a very smile-less American couple, instead of a friend from my group, or even someone who spoke German. So, for kicks, I pretended on the entire flight that I only spoke German. I'd talk to the stewardesses only in German, and I'd occasionally mutter some German things if I felt like it.
They didn't realize until nearly the other end of the Atlantic that I spoke perfect English .
