Once physical levels are gone, will racial stats start to matter?

[Jobeto-Rin]

Exactly.

And from a gameplay standpoint, there are plenty of people (like me) who want to play as a physical attacker Lalafell, just like there are people who want to be a spell-casting Roegadyn.

& that shouldn't be impossible because of choiced character leveling progression.

but a level 1 lalafell should naturally fit into the role of a mage better than a roegadyn would.

I'd imagine a roegadyn that is supposedly naturally stronger would knock your lights out waaay faster than a lalafell ever could.
