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

Hm? My argument is that a) 2-3%, even 10% increase in healing won't be the reason your party fails or not;

This is the only part of what you are saying that I disagree with, 3% isn't a difference you'll feel but it is a difference. There are some very nasty straight up throughput challenges such as having the two dreads up at the beginning of t4 phase 6 where very bit helps, and the rest of the time that 3% might just be the cushion that lets you survive small errors in judgement or hiccup because of lag. Every little bit helps.

But anyway, I think we've kind of sidetracked things here. I think the main point that needs to get made in this thread is that when you are deciding where to spend your mythology tomestones your current gear is mostly irrelevant. You don't compare the difference in upgrade from relic to +1 against ilvl55 to af2, you compare darklight to af2 because there is no rng involved in getting darklight.

And yeah, no one is being carried if they are contributing in a meaningful way, even if their gear is a little under par.

I don't think this is a tangential discussion. It's vital for people to understand that the contribution of equipment upgrades is minuscule compared to the importance of skill and execution. Taking damage, making mistakes, or failing to address mechanics is a much greater pull on the party than being undergeared.

That being said, even the smallest percentages will, over time, manifest themselves in success rates and overall impressions of battles. There's no excuse to being undergeared if the rest of the party is well-equipped, understands the fight, and has mastered their job.
