I can understand low level gear having some model overlap

[Gesser]

and my point was if they can put that much effort into gear that very few will even get, why cant they do the same for gear that a large majority of people will, namely tome gear.

I spoke to that, incentivization.

Also reward. The people who put in the hard work & the effort, slaving away deserve uniqueness moreso in my opinion.

The entirety of the general populace has easy access to Tome gear, so a generalized set is more suitable.

Additionally, helps if you spell out your point a bit better to begin with... that literally didn't come out whatsoever in your original post.
