Hi there Freyjaa!
Glad you are not neglecting your Horde needs, and it is admirable that you play
Alliance for your mom. 
I’m assuming you need the guild for the Hord BElf?
I can tell you that Revered with Death’s raid times work out for you, we raid Fri/Sat 11pm server (EST).
We’ve had some setbacks due to fighting the attendance boss, but we are pressing our way through H Dazzle (BoD). We just keep plugging along in our attempts to become Exalted with Death 
Every expansion we push into Heroic raiding, we may not always get AOTC…but for us it’s more about having fun and learning the fights rather than muscling everything to the ground in order to get a title.
We like to run keys for sure, and have quite a few that push 10+, although I will be honest, sometimes it’s difficult to find the bodies.
Here is our guild spam if you would like to check it out [H]Revered with Death - What's your End Game?
At the end of the day we’re just a bunch of nerds that love playing this game.
