Jugg tank, 2sorc heals, 2 merc, marauder, assasin, sniper.
Shield is good if pillars bug out btw phases because pillars are killed in wrong order and end up with aoe blasts.
Our kill night three major bugs were present:
1. Ball double tick - popping a ball would result in an aoe tick after its explosion. Meaning most would take approx 15k damage per ball. Work around - healers on top of game, smart use of defensive cooldowns by all
2. Soa would always toss The top name from The ball targets precsding The toss. Sniper died usually, used The brez.
3. Bubble no pop P3. When we got The "perfect" 4 bubbles he died.
If people are dying to balls, it just means your group needs more attempts. Eventually you will get to The point where you are clearing to p3 consistently and just waiting for The right RNG with bubble bugs.
