It's about time to add Coil story mode, isn't it ?

Really? Thats great. How many tries did it take? You think you could repeat this miracle? I dont think so, most of the runs i got into dont even got to snakes (and thats a lot of runs).

3 times with PF/FC learning party
6 times DF.
The last DF I managed to down it and it wasn't a miracle or what lol.
And FYI, in at least half of those tries, I was actually part of the reason why the party failed.
I'm quite sure I can pass it again, since many people in my friend list/LS/FC downed it through DF and to be perfectly honest, many of the pugs in DF actually knows the fight better than I did .

In many cases, people just don't notice when they are actually part of the problem.
People tend to overestimate their capability?
I'm not saying this applies to your situation, but this could partly explain why so many people complain about pugs ruining their chances in DF, not realizing they might be contributing to that result.

To go further, if there are so many skilled players who are still stuck at T5, they shouldn't be still stuck at T5.
Why? Because the duty finders is bound to match the so called skilled players together and they should be able to clear it.
If a lot of people got problem with T5, it means DF for T5 has lots of players without necessary knowledge to down T5.
Though so far from my experience T5 DF is actually quite good.

By the way if you are stuck at T5 and feels like you know the fight, why don't you ask your FC to help you?
Many FC help members get through content, especially those without lockout.
