If you want to RP on this character, I´d suggest these guys:
The guild is part of big RP community called PCU which has over 20 guilds (so even if you want to RP another race, there´s plenty to choose from) that will be doing raids on both Alliance and Horde starting Shadowlands + has plenty of players who like doing content (and are really good about it) who you could also team up with for some PvP or M+ if that´s also your cup of tea.
I´m just a filthy casual so I did not take part in 8.3 raiding despite being part of the community, but I think people managed to clear Heroic on both factions.
