Post after post about non meta specs getting declined for hours on end. Believe it or not there is a handy tool in the group finder that allows you to start your own group to do mythic dungeons and the best part is you can accept whoever you want!
And before you tell me that you don’t want to make your own groups, let me stop you right there. START YOUR OWN GROUP. It’s a night and day difference as the majority of people don’t care who they run with.
I did the majority of my mythic plus runs as sub by making my own groups. After getting declined like a lot of people repeatedly for days, I decided enough was enough. This is what you must do.
The people who are declining you are getting dozens of applications. They are going to pick the highest item level person. So if you want to gear up you need to make your own standard and make your own group.
Repeat. Make your own group. Stop being lazy.
Make your own group.
