I just wish the Binding Coil was longer. I think it's a fun dungeon so far, but it's way too short and sometimes pointless (Turn 3). Turn 4 is just an elevator gauntlet, Turn 2 is a different kind of gauntlet, and Turn 3 is pointless. The only Turn that feels like an actual raid with some minor exploring is Turn 1 because it's more than just one boss room. I was also thinking Turn 5 would be a bit longer, but it's just the boss room basically. To be honest, I was expecting each Turn in Coils to be a mini-dungeon, but that isn't the case at all. Turn 3 would be my favorite because there's some exploring and neat mechanics in place if you actually had a reason to do it (no loot, no tomes, no bosses, nothing at all). Looking at Turn 3, I'm not sure if SE understands what makes raiding fun, lol. (although I admit the jumping around is fun - my LS and I have made a race of it - we speed run Turn 3 ignoring every mob and first one who makes it to the bottom wins). xD

Anyways, I think Bahamut's Coil has been a disappointment so far simply because of how short it is. And I'm a little worried that it will be another 5-6 months before they add new Turns since 2.1 is Crystal Tower (easier than Coils).
