There are 3 servitor plates total(the plates the servitors try to sacrifice at in phase 1 and 2) but every time Aksis teleports, only one plate will glow. So one empowered guardian will slam Aksis while another will slam the glowing plate(it will have a beam of red light coming out of it) every time Aksis teleports there will be one random guardian who does not have to slam anything, although they need to be ready, just in case, as it's completely random where aksis will go and which plate will glow. The way my team did it is we had 1 empowered watch the servitor plate and Aksis spawn spot on left(just stand in between the two spots, it's easier) And had another empowered person do the same thing on the right side. As for the 3rd empowered person, they watched back mid servitor plate, this is the easiest because it's the only servitor plate that Aksis will spawn on top of, so they only had to watch one spot. As for the middle Aksis spawn pretty much every one would keep an eye on it. If you don't have anything to slam on your designated side, start looking to help out the other spots as it does get hectic and they may need help. One last thing, if we had double empowerment on one side we would switch immediately after killing captain and clearing shanks. Excuse the wall of text, I hope this explains it a bit better It's kind of hard to interpret bungies insane mechanics through text but good luck everyone!
