Hi Arcaneaux,
There are quite a few guilds with that will meet all of your needs on your list, but the only way to find out if you’re compatible or not is to test the waters and get in touch with them /nodnod.
Something to keep in mind, sobering advice, BfA is quite terrible. I think most folks are willing to discuss the facts, but for this post’s sake, role-players largely hate it. Whether or not guilds on this server role-play or not, the overarching story of Sylvanas, war-crimes being picked like dandelions, the horrific writing, and the god-awful systems (corruption being the latest 
), guilds are hurting. Communities are going dormant til the 9.0 patch.
Start with the WrA directory to begin your search. Keep in mind also: not every guild uses the forums. There are some Goliath guilds on the red team that never touch this board. Here’s two guilds that I think will set you on a good searching path:
-
Pyreanor, a small guild focusing on slice of life and semi-hardcore raiding.
-
The Grim, a very old guild that many veterans of WrA, Twisting Nether, and Ravenholdt (and Emerald Dream) talk about from time to time. Very anti-Alliance and a lot of PVP on the forefront, but great players who raid competitively (heroic mode).
If you have any questions, don’t be afraid to ask and don’t be a stranger. Here’s hoping you find your Goldilock (it’s juuuust right)!
