We're not 'behind,' we're following DMM's release schedule very closely, just with about a year between start dates. DMM would never allow anyone else to release a game of theirs to run concurrently with their own and steal some of their customers. Besides, we have the advantage of knowing what's coming up next.
Normal gacha will always have a place. Eventually we're going to be doing nationality battles and nobody has a full roster of 5*s and 6*s from a single nation.
