In short, the lore of the cards themselves (as well as what was "supposedly" changed) remained intact.
Not to mention that AST still relies on cards as its main mechanic.
What the OP and you suggest would be akin to removing the cards from AST or the faeries from SCH.
Besides, drastically changing lore because some people don't like an aspect of it is a (huge) slippery slope.
Where would that end?
Especially since one of FF14's main strengths is the consistency of its overall lore (class/job included).
