Great! - unplanned patch - in peak game-play time - without any prior notice - description/info promised but not provided Did I forgot anything?

Hi all, I have a simple question (maybe a stupid one, but I was unable to find an answer here using Search): - how are individual players ordered in the Operations group? Is the "creator" on the top and others follow in the same order as they were invited? - could this list be re-ordered (to put tanks on the top, healers on the bottom, etc.) Thank You in Advance for You answer
