The point the STO guy made was not that VO suxs, but rather that doing it 100% for an MMO is probably not the best way to spend your dev budget, which I would have to agree with. Does it matter if VendorA, VendorB, VendorC etc etc all have voice. Not to me, I'm gunna skip it everytime.

For example if you only budget for 50% VO, then you can spend that other 50% on something else, like adding an extra gameplay feature or whatever.

Ofcourse, if your budget is big enough to afford everything, then "make it so"....
