Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Idk how to show the picture, but the coil is on thisisbwscgsalt (This is bluewhitesilver/champion gladion's alt) I have 2800 coil.
I am voting Ban on dragonite.
I have 3000 coil :D, It's on the alt Bluewhiteduck2A.
I vote Do not ban Because Cresselia isn't that hard to counter with for example golisipod and other bug or dark types.
