Hey Rambozzo,
Like others I am note sure if you are interested in switching to the Alliance but I think we might be a good place for you to get back into the raid scene.
on US-Lightbringer is a AotC Heroic Raiding and Mythic+ guild. We are midcore so we don’t fall into the strictly casual you are looking for but we are not oppressively hardcore either. With a great Discord and wonderfully inclusive community we do strive to have the most fun we possibly can, though I am a bit bias.
Outside of raiding we hold regular events, from movie night, to transmog contests. If you are interested in checking us out more check here:
Or just drop me a line, you can reach me on battle net at Aya#11373. I hope to hear from you soon!
