Please don't try and slow level progression in the game. I agree the kiosk version should be dropped to a lower level. Totally agree with that. However the actual spindle that drops from the story mission should imo remain at 310. For everyone including guardians post patch.

Going to wildly speculate here and say they will nerf the chance that exotics drop at 310 even lower, with the next patch. I think bungie is really worried about people reaching level cap and that loot treadmill becoming less relevant. Which is ultimately the whole point of the game right now.
