Def use the spread out strategy on the people taking out the supplicants in the last room.
Spread out the team on the last templar phase so you kill the random oracles as they appear and you'll never need to worry about relic holder cleansing
On oracle phase make sure you've got one person on each side looking for the hidden (front) one's, as they can see it from each others side
On Atheon burn phase start to move at 5 secs left on times vengance buff to make sure people don't get teleported by accident
Mostly shit you already know but worth saying! You got this guys, time to bring home the bacon!!
