Ultimatum modifiers clashing with boss design

Certain modifiers in Ultimatum do not feel fair or designed with new boss attacks and mechanics.

All the mods that add environmental hazards are fine only when it's a non-boss fight.

It's incredibly frustrating if you get impending doom while trying to fight a boss.

If the environment mods don't get reworked, at least let it be disabled during boss fights. It just doesn't make sense to have them in a static arena with bosses that have invuln phases and their own dodge requirements.
