Hey! 
This is the exact reason I call MG home. Its so lively and everyone I meet here is great. The random interactions and parade of tree ents in Dornagal are super fun.
League of Danger Noodles is a super casual guild. We’ve knocked out Normal, and are popping into heroic. We’re currently 1/8 H and casually going to go towards AotC. But we’re not going to stress about it. We’re a bunch of casual peeps honestly. Maybe we wipe, maybe we don’t. But we’re not going to get caught up over it.
We raid once a week on Fridays 8:30pm EST to 10:30pm EST. Depending on your definition - that may or may not be the weekend >.>
We host one Mythic + group. And another has been attempting to form - but a few of those people have IRL stuff going on (and IRL always >> over WoW). But we usually jam for sure.
I know some of the things you mentioned and my responses don’t exactly match up 100% - but I figured I’d post anyways. Since at our core we’re a casual bunch of friends who just love playing WoW. And we never stress over it. And when we do we take a step back. This is our OG guild recruitment post (note we no longer do the saturday morning raid - again IRL >> WoW).
