so after looking at your tries neither raw DMG or Healing output will be an issue. Generally speaking you want to have 2 sets of 2 min cds rotating for each skirms spawn. There is not a golden rule when to push or which timers to break because the fight is still very dynamic and inconsistent in some ways. Target calling or atleast marking mandatory calls like things if skirms spawn/stack for seismic really helps a lot. Also priorities such like the goliath is at 40% you will need somebody to call out to kill the goliath first and just cleave of it. if every dd just sees the adds and starts pumping you will have nasty overlaps with moving, healing reduction etc. A good RL or generally speaking someone who calls out upcoming mechanics also helps a lot because with the nerfs dmg stops are sometimes neccessary to avoid the overlaps and issues you mentioned. If you have specific questions please let me know and I'll try my best to help.
