As in Orcish, common etc.
Since adding more professions would be like pouring acid in to a gushing wound for a solution, I suggest we get to become more proficient with a second (or third) language for our character that isn’t native to the race you play. There is already a few ways to communicate with the opposite faction, including an inscription item that straight up allows cross-faction communication.
Cross communication could be disabled for instanced PvP, but for pretty much any other scenario you can imagine, they should be enabled.
That’s just the suggestion part of it.
For this to be something that isn’t just another box to tick off, it should take commitment - not quite like real life, but at least to a point where you don’t just do it because it’s an easy addition to some completionist complex.
Speech could be conveyed with an accent: In fact, there should always be an accent. I know some people acquire proficiency to a point where they almost eliminate an accent entirely, but this also needs to be fun. Slight mispronunciations should still occur at maxed out proficiency imo.
This is pretty much exclusively an RP thing, but one that I think many would enjoy at least a little. Shouldn’t take too much to implement either.
Arguments against it: Toxicity? Well, like I said, you can already communicate via items and there’s even a third-party website that allows you to convey a fair bit of coherent text to the enemy faction player.
i.e. people will find ways to be toxic regardless. Not a good counter-point towards a nice chunk of RP potential added to the game.
Anyway, it’s just a small idea that I think many have considered before, but devs are still weirdly reluctant about adding it.
It also invites opportunity to revise Pandaren, the infamously stupid “om nom nom” speech.
