What is the "recommended" gear to enter each Turn of Binding Coil of Bahamut?

Yes, I DPS in phase 4, but it has nothing to do with my gear. It's just that the party takes almost no damage in that turn and doesn't need healing.

I'm really having trouble finding the consistency in your argument though, if you don't have the time to dps (which is perfectly reasonable and expected in much of coil) you should be happy to get a 3% boost in throughput.

An upgrade is never useless, if you already meet the base requirements for your job without it, then it will give you more margin for error, or allow you to exceed your base role.

Hm? My argument is that a) 2-3%, even 10% increase in healing won't be the reason your party fails or not; b) Using your abilities correctly is much more important than gear. Both arguments obviously imply that you wear the minimum required gear to keep your party alive.
Other than that I'm just pointing out stupidities of others in this thread. (Like saying that there is always someone who gets carried.)
