Hey there! I know you said two different characters but didn’t list the classes, however just on the slight chance you have a Warlock our guild as an opening for one and we might be what you’re looking for if Alliance is okay.
We’re a semi-hardcore guild on Alliance Turalyon that’s been around since TBC, while we aren’t a hardcore CE guild we still like to have fun while getting serious for the bosses that need it, we raid Tues/Weds from 8-11 pm EST with an optional night that usually just turns into an alt night on Saturdays in the same time frame - as of writing this we are currently 10/10N and 4/10H.
I’ll leave more of our info below but if this sounds like what you’re looking for and times/days/Alliance is all okay then please fill out a short app on our guild site, hope to hear from you and if not then good luck in your search!
