Castrum Fluminis is way too difficult

[Zanarkand-Ronso]

I know this will upset the hardcore video game players in the game but this fight is way too difficult, and is a huge gate in the MSQ. Have developers considered nerfing the fight? The instant death mechanic from the half moons is very unforgiving and is an extreme steep curve in difficulty compared to the other fights you've done. Shinryu and Yotsuyu are just such a sudden jump in difficulty that if your healers are both new to the game you'll be stuck in that fight for two hours. I hope the developers will nerf them (give 50% echo right away maybe?)

Is the Moon Mechanic the only thing stopping you from Completion? The fight honestly isn't hard, it is...time consuming.
But for the Moons literally, just dont let yourself get 5 stacks of Dark or Light. At 3- 4 stacks just go to the other side, and it resets to a new stack. You just do that until the Mechanic goes away. Don't stand in one area too long basically.
I think asking for a 50% echo nerf is asking way to much.

And its not a Hardcore Elite Gamer thing to say ""play it, learn it and overcome it""
That applies to anything and everything difficult in games. And even in life. Not trying to punk ya or be mean, but you have to Play it to learn it, and learn it to beat it.
Therefore -> Overcoming it
