Please no more Eureka!

[Beckett]

You clearly have no idea how battle design works. Forgetting the new attacks and animations, battle content needs to be scripted, balanced, and tested. While I agree with you that Eureka took more assets, the whole content series is an experiment that benefits the game even if its a failure. The logogram system, the magia board system, the public dungeon system, and the open world instance system can all be reused in different ways now, and wouldn't exist without Eureka.

The battle design argument goes out the window now that BA exists.

Come to think of it, there's also all the FATE bosses in every zone. And while I'm sure developing fight mechanics for a FATE boss is far less effort than an Ultimate fight, there are a lot of FATE bosses that all had to have effort put into their mechanics.
