Hey Arianne!
My new, 2 month old (& some change) guild, The Legal Bananas, on Alliance Stormrage might be the type of atmosphere you’re looking for! We are a tight knit group of individuals who met on various places such as Gamer Pals subreddit, WoW FB groups, knowing each other IRL & meeting on the wow forums!
I would consider myself a veteran player, since I’ve been playing since OG BC, but my cogm has a different outlook, as he’s only been playing for a year & came from FFXIV. Together, we run the guild & don’t let there be ANY bullying or nonsense such as political or religious convos in voice chats.
I try to keep the guild as active as possible, meaning I do a guild roster purge every month & remove everyone who hasn’t logged in in over 15 days (if you need to take a break & don’t want to leave, tell me, & I’ll make you DO NOT KICK!) I do this bc I want the guild to be active, not an alt parking lot for people who play elsewhere.
We just started raiding last weekend on Normal Seplucher. (We DO hope to get AOTC, but since we just started raiding, idk if we’ll get it for Seplucher? We might just shoot to getting it in Dragonflight, instead!) Everyone did amazing & I actually got choked up when we finally killed the 2nd boss after struggling on it for 12 attempts. I was so proud of everyone! I never really raided & to see everyone come together & use teamwork, it really amazed me & I don’t know if I can fully describe my feelings about it!
In TLB, we are in discord voice chat even when events aren’t going on. The guildies who use voice chat are very close & know private & personal things about each other! I love getting into vc at night after a long day & shooting the sh!t with my new friends 
If you’re wondering what we need for the raid we really need a dps shaman & maybe another dps dk. But def play whatever is the most fun for you!
Anyway, here is my guild recruitment spam if you wanna read it!
If you have any questions or comments, please feel free to DM me via discord anytime: FluffyPanda#6738
I cannot wait to hear from you! I hope you have a wonderful rest of your day!

P.S. Since my guild is fairly new, we have a lott of people who are also new to the game who are going at your speed! For instance, my cogm likes to take it slow & hasn’t really decided on what he wants to main yet. He really enjoys tmog runs too! I think you’d fit in well if you gave us a shot
