Other than that whats the deal with low res textures anyway, lightning effects is the important thing here. We re in 2014 and Pixel Art games are also still a BIG deal. Not everything have to be top notch on the pure technic side.

It's an aesthetic clash. Pixel art games don't need to look particularly good because they can more easily pass as a 'art design choice', which they often are. ARR goes for a realistic look, though, and that's why pixelated textures are a bad idea: they clash with all the other aethetic choices. If you go look at a wall in Ul'dah or at your character's face, you don't really notice the pixels the same way you do with armor. Maybe if you zoom real close to your face you'll notice the pixelation, but for your armor? Go put on a dalmatica or a cowl and look at the pattern. Or with the Darklight cowls, too. If you don't notice the pixelation with those, then you probably will never see any pixelation ever.
If you want to notice the difference, you could go look at Minecraft texture packs. Find one that is 16x16, and then find one that is 64x64. Tell me you don't notice the difference. You don't even need the game, since texture packs often come with screenshots.

Also, they could give high resolution texture support for the PC and the PS4, even if they can't do that with the PS3 because of its limitation. There's nothing stopping them from doing that.
