I'd wager that every last person who has labored on FFXIV since the launch of the open beta knows that for current needs, what they have is inadequate--from YoshiP on down. Almost certainly they need more/better machines, probably they need to hire more people to work with these machines. And likely if this inadequacy seems glaring to us, behind the scenes it's even more alarming.

Unfortunately, YoshiP cannot print money. He'd need permission from his own bosses for budget increases and probably also to hire new people. Even assuming this good response to FFXIV:ARR is prompting an increase in his budget that can go to servers and employees, it may not take effect for quite some time (fiscal calendar being what it is), since, well, SE's CFO isn't only funding FFXIV:ARR, but dozens of other things as well. So screaming at the FFXIV team to fix this problem is less than helpful, since they're probably pleading with their bosses for permission to have the resources to fix this problem.
