The Tarren Mill invasion bugged and didn't start, so everyone was left standing around doing nothing, hoping it would fix itself (it never did). During all of that, someone Horde-side mentioned in a yell (in Demonic) that Demon Hunters can speak cross-faction with each other using the language. I was skeptical (because nobody responded to him) but it turns out that you can! We all sat there shouting in Demonic for about 20-odd minutes before I suggested we group up outside of town so we didn't have to yell lmao (and since the Alliance couldn't land because they'd get attacked by guards and flagged too). That ended up with me and a group of around 7-10 other DHs going to the bridge nearby and chatted for 3 hours.
Then someone got the good idea to RP walk on their Felsaber and everyone joined in. We had some problems with phasing at first in Arathi, which got fixed through grouping up Horde and Alliance together in two separate groups, and we also ran into problems getting into the Wetlands (fixed with a PVP combat glitch to stop realms from phasing). New invasions eventually popped (shows how long we sat talking about random things on the bridge lmao) and we all managed to get to the Westfall one okay (with some hiccups in it, because PVP flagging and ganky people) but unfortunately Azshara wouldn't cooperate and the Alliance group all went to bed afterwards.
My group of Blood Elves all hung out in Gallywix's Pleasure Palace in the pool, until today's realm restart to fix the latency issues got pushed and ruined the fun.
I honestly thought (and still think) that the cross-faction speak will cause a lot of shit-talking to happen (especially since it apparently won't be disabled during battlegrounds???), but I am so glad that I was able to find and btag a group of really chill, awesome people because of it

(If this isn't the right forum for this sort of thing, I apologize! It was just a really awesome moment that I wanted to share (also it might not be well known that Demon Hunters can cross-faction speak because I sure as hell didn't know l-lol))
