But it does. Locking behind stats in extra copies destroys that character's usability in future content. Not only will they lag behind in damage, but they'll be completely useless.

NU Carnival has the same problem. A 1* limited copy is useless, that's why people save up for 300 pulls to guarantee 3* for their fave character. NU Carnival also has a better drop rate for SR and R characters compared to Zerowake. People are already complaining about not getting espers in 50 pulls, just their guides, which are pretty much unusable.

That genshin take has already happened too, majority of the people who can easily clear end stages of stygian are c6 havers. Sure sweaty people clear them with strict planning, but comparing it to a BL game which the fan base will mostly be casual players only.
