There is one way between only 3 guys dunk 3 and 5 guys dunk 3. One Guy can close the the pyramids and one can close the circle. The other 4 can pick up 3 resonances.
Besides Forbearance, freakin Buried Bloodline made me unkillable with Void Hegemony and Expanding Abyss. I also used Indebted Kindness with Voltshot too
We did a third variant, mid locked out all three. 1 player grabbed 1 of a symbol to match the single totem, and the other grabbed 2 matching the other two. This leaves the 4 players on the sides with 3 resonance each. Glaives are also great option besides forbearance. They one shot all adds and use can block with the shield if you’re getting attacked. The new one from the raid with recon chain is amazing
Nope you can do it with just 3. in terms of how the encounter normally works, its just more resonance = more time added back on the clock but even that has a limit where it won't give you more time back no matter how many stacks you have (for example I believe encounter 1 only lets you go to 4:15 max time)
I feel like it would be best to just have one person lock all three Call out what each side needs and leave that single node on the ground and then the whole team goes around as a 6 man clearing plates and closing all of them in one go
