Some of you people seem to think that because you can't play the game on maxed out setting the people who have a more powerful PC (like myself) should have to suffer
I'm pretty sure you're the only one thinking that. In other words:
Making the game accessible to lower performance PCs != Lower the quality on high end machines. In fact, it should only improve
the quality of the game on high end machines since the missing optimizations that need to be there for low end devices should allow good GPUs to push the boundaries even further.
Also, the more machines FFXIV can run on, the more players can actually play the game, and the better chance your expensive rig will actually be able to see FFXIV running because it hasn't shut down for lack of players. So, really, this is not a waste of time at all, but rather entirely in your best interest in every way.
