Now, I know this is a very long process in real life (I speak both Fluent English and Elementary levels of French and are currently learning Cantonese, which I blame Sindome for by the way!); However, I feel like the balance for languages is insanely out of whack. Especially considering the costs and although you aren't spending actual UEs, since they don't count towards your cap, learning a language IC can really jank you on learning anything else for a considerable amount of time (Or not help when you hit that curve if you dip partials like I do when I'm not fully dedicating to learning a language.)
Languages are complicated, both in game and OOC in the real world. I know someone can spend years learning a language and only grasp half of it. I also know your stats play a part in this, but it still feels like it's a really long haul of crippling yourself because of how our UE system works, when you could be doing other things. This discourages players from learning languages sometimes.
My suggestion is this;
Nerf the intelligence requirements for learning a language for the UEs to wrack up on it quicker, or simply drop the price for languages to a more reasonable rate. (Currently 1 UE gets you 2% of a language on ordinary at meaningless, and since this is a multi-tier thing, that requires a massive investment this feels a little too high. Especially considering some of these languages (Mixmash, Talagog and Japanese specifically) are ones we are exposed to near constantly in Withmore.)
People tend to pick up words from other languages if they spend enough time around someone speaking that language, so another minor (and less likely) suggestion would be to perhaps add an incremental increase in your knowledge % of a language, which increases the more you hear it (Higher int = more % learned from people talking it, should be vastly slower than actually UE dumping) This would also encourage a type of Rp that I personally haven't seen exist. Folks taking chyen from others to tutor them in a language they're fluent in.
Sorry for the rant, just a thought!
