On patch day I completed all of the new Eden Raids...when it came to E7, well...we had a color-blind healer and the other had glaucoma. During the purple and white circle phases, things would go south pretty quick. Neither of the healers could identify what portals were being shot into first either. My struggle with the fight is I feel you can't zoom out enough to see the entire arena which resulted in blind spots for me, however, we kept wiping after the AOE check due to healers dying.
This party had 20 wipes before we realized it was hopeless. My second party wiped five times but we completed it. At least I have this fight and its mechanics memorized at this point. Ooof.
