Is cross faction mythic raiding available right now? I’m planning on going mag’har here in a little bit but my raid team is currently all alliance. Will I be able to mythic raid with them if I faction change or no?
yes
the only caveat comes with server xfers. if you start a raid week (and thus get a raid lockout) DO NOT transfer until your raid week is complete, because you will be locked out even from the same group.
so just do your transfer in between raid weeks, and you’ll be fine.
