While certainly is an ethical choice, I just can't see them hire VA to voice all of WoL's dialogue choice line in both economical and efficency sense,
the most realistical thing CBU3 could do is pay some VAs for their voice sample, use AI temper it, then distribute it across the playable race.
But then, SQEX might start getting greedy and cut the VA budget for FFXIV MSQ development.
Quite a can of worm out there if I say so
