Learning other languages/racial abilities through a grind - Winderpelt Furbolg grind

Hey! Sorry if something similar was already posted, but just wanting to share my thoughts on the new faction/grind they added.

So I loved the idea of learning a whole language through the Winterpelt Furbolg faction. It was a short and easy grind with a nice little quest line to go alongside it; arguably, the most interesting reward being the new language you learn throughout it. However, I feel as if it is a bit of a wasted idea as I dont imagine us using this language in many scenarios despite it being such a great idea.
So I propose that we have other grinds in the game that let us learn all the other languages. It would be easy to implement and, seeing as the horde and alliance are pretty much friends anyway, it would be nice to be able to communicate to them cross faction in the world normally.

Furthermore, Savix had a great idea where we could possibly learn other racial abilities throughout a similar system. This would allow players to play whichever race they would like without having to worry about mid-maxing for stats. Ill post the video here to give credit for his idea:

Overall, it provides content that is OPTIONAL and I think it would be a great addition to the game.
