it's kinda disappointing to see your set getting slowly push down the page as newer sets appears. and see your effort being wasted. but i won't give up, gonna keep going, not gonna give up till at least one set are put into the game. going to make a naga set now.
It's pretty random. I just had a HUD, Ward, Ability Icons from a set in my queue. The issue is that older sets aren't using the new set feature in collections which is still causing each item to be put into the queue individually rather than one Yes/No option from the collection if its ticked as a set.
