It is a pain but i feel checkpoints take away from the point of Coils. If it were a huge raid with loads of bosses and paths i could sort of agree but then how do you set up checkpoints in the context of PuG's where people have varied experience? Even in DF when somebody sets up a "down party" they wipe on meteors because people just join expecting they can hide in the crowd and be carried. When people are not all in the same place what enforces checkpoints? If you drag randoms who have never done it to the middle of the fight do you think it will go any better? The only way to make progress in this case is to drill people in all aspects of the fight.

I share your frustration I've tried several PF groups and got to the final phase then still wiped even though by that point you should be able to brute force your way to the finish line with any party through constant resses there is like one thing that can wipe the party. There are derps that can happen I have my own derp on the second heavensfall I often get the debuff from the add and want to clear the stacks in the white circle but then the heavensfall lands on my face right after it sucks XD.
