I guess we all are interested and following the story in the hope of finding out more of the detail. Whatever that final story might be, it is untenable to posit that Boeing intended the system to function as it did in the two mishaps - clearly, the FMECA exercise didn't pick up some potential problems which it ought to have done. The folks involved, and the company, are going to have to wear some censure as a result.
However, in respect of your observation it needs to be kept in mind that LSS, basically, is stick feel as perceived by the pilot.
As to the detailed design considerations for MCAS, I don't think that sufficient information has been released yet into the public domain so, in my view, there remains much waiting for further details.
