Our guild just finished the first tier 7. First one we didnt finish, this time it was easy. We have two guys doing the first phase which is way easier than 6, then have the other guys go in with one team unless the door is close then u can hit twice. We had like 40 players doing damage... it is a question of how many good enuff teebos u have... just one guy in our guild can bring rex... we only can do one raid every 3 days, and i think if u are thinking about it, try it, its only 60k.
