I am a part of an alliance heroic raiding community that has some openings for 9.1. As it is a community, it would not require a server transfer if you wanted to give us a try and see if we would be a good fit.
We generally run a 10-15 man raid team, currently looking to build back up to 2/3/9 (ish) for the upcoming content. Our progression is generally to aim for AOTC, we do not mythic raid. Our group has fun running keys in the 10-15 range after raid and whatnot, but it’s certainly not required.
If you think that a community might be what you and your friend are looking for, check out the link below for contact information and more info about our group.
