LF Organized Wpvp / Military rp

Hello there! While I am new to roleplaying, I’ve always been fascinated by the prospect of large armies fighting in WoW, especially in classic (and now that i’ve gotten roped back into wow lol)
So uh, even if you aren’t in a guild that is about this, I would really like to know which server and which faction. Well, hopefully factions
Thank you very much!
