Hi Loro,
I wasn’t too sure if you would be willing to move servers but thought it would be best to give it a shot. Our guild Braveheart (Argent Dawn/Alliance) is a social guild which enjoys doing raids, dungeons (including m+), some roleplaying and in general questing and achievement hunting.
All of our members are likeminded and want to have fun while playing the game, without the random kicks from finding random groups - just a chilled environment where you can enjoy the game, make some new friends and chat while playing the game.
Unfortunately our raid team is full at the moment but for dungeons we usually form our own groups within the guild and have chill runs which can include pushing keys or just gearing alts and newly leveled characters (which I think may appeal to you!) - we have our own channel on Discord where we can chat outside of the game and often use voice chat for dungeons (but not required).
Check out our forum post here for some more information or if you’d like to chat, add me on battle.net (Hystericxl#2223) or discord (Hystericxl#3376)
