Quick question, I am going to try going with myself, and 2 friends. There wil be a mage and 2 rangers. We only want to let the mage take Rex, and 2 rangers take Prime. What would be the best strat upon entering the lair? The two rangers go after Supreme (only for first kill if he comes after us) and Prime, and then let the mage get to his spot for rex? Any help is appreciated.
