They already reverted the Escalation change past Trial 21

They actually removed Permanent Damage and No Revives from Ultra II after the backlash. The Broken Reagent is still gone so Escalation is slightly easier now and Heal Rig is viable again.

Still, they're gonna re-add them when rebalancing on how the difficulty curve works so I'm expecting the upcoming change is gonna put maximum difficulty into Trial 50 instead and it will be as difficult as Trial 21 from now on.
