Yeah, they should've just went with simple QoL changes than give an overhaul. They could've improved upon the "annoying" parts instead of trying to fix with prevention, which unsurprisingly made things worse.

Like for Demi-Bahamut for example, we can't use ogcds to trigger Wyrmwaves now because they probably thought it was annoying to wait for Aetherflow before summoning him, and it was. What they could've done was make Demi-Bahamut give us the ability to use Aetherflow abilities without the need of Aetherflow stacks. Really anything that would promote using ogcds in Bahamut phase which made it fun, while making the process less annoying.

I'm not a pro SMN so I'm not too sure if it's a good idea but just throwing it out there.
