Dawn of the Infinite help

After trying and failing both dungeons 10+ times this weekend I’m just looking for some advice. I understand important mechanics and know how to tank each boss, but I can’t seem to work around the dps. Even people with 3k+ io have needed to be told what the bosses actually do.

Is there any way to make this easier? Really just hoping there’s some adjustments I can make to help the dps.
