Four things that i would nerf/change, since they are the most frustrating things about this fight.

Doom:
Increase the timer of doom from 4 to 8 seconds before you die, gives healers a bit more time to dispell.

Platforms:
increase the time before a platform breaks from two people from 1 to 3 seconds, so you can actually react to people doing a wrong move.

Tower Damage:
Reduce the raid wide damage from failed tower stacks by 30-50%

Resurrection spots:

If someone dies make their body spawn at the correct side where their party is.

Group A West
Group B North(?).
Group C East.

(I have over 80 kills on this fight.)
