If you have this kind of attitude towards people you raid with that you’re the competent one and they aren’t it’s better you move on from raiding. Especially since you’re a boomkin that doesn’t innervate or find a good guild. Every guild isn’t going to do hardcore progression especially dads that have families + work and still make time to raid.
I’m a late millennial verging zoomer and I enjoy my dad guild (i’m 27 and the youngest guy in the guild, lol). It’s relaxed and even though we’re 9/10 it’s okay. It’s tricky content that will only get easier next phase.
