Why don't I get invited to TW raids?

I sign up for TW raid groups but never get invited. It can’t be ilvl since that doesn’t matter in TW raids. What could it possibly be?

They fill really quickly. Try refreshing the group finder until a new one pops up.

what do other people who get invited have that you dont? take a look at a few and see how you compare.
