The Devs apparently learned very little from the bad aspects of Eureka.

What I particularly think it's a mistake repeated from Eureka is delevelling when you die. It's literally the reason that kept me from even trying Eureka this whole time.

The delevelling only happens if you choose to just respawn at base, and not get rezzed by another healer or someone with the Raise-L logos action. If you get rezzed by someone else, you keep your Elemental Exp.
