It seems that some folks like to use Around strictly for RP while others like to use it to chat (often OOC) with un-teamed homins in the immediate vicinity without the hassles of making teams or leagues that dissolve as soon as the conversation is over. And that has led to a bit of conflict between those who have differing views on what Around is really for.
I'm not quite sure how anyone couldn't just form a cohesive, grammatically correct sentence. Because that's literally all that's needed to have it pass for being RP (even if it's not intented as such).
So instead of trying to come up with even more complications for the game, rather teach people some basic linguistic skills maybe?
