This is funny in a way. Heals and other mechanics other than DDR being needed is actually good. But that's where it becomes interesting in content that doesn't guarantees certain roles of the trinity to play along the system: in Eureka/Bozja you could just take logograms or lost actions to alleviate your survivability, but here, you can't.
Now if was willing to indulge in some doom posting, watch SE permanently delete survivability requirements like they did in deep dungeons instead of fixing the damn problem...
