Umm I have nothing against him I quite like his style. I like his style more in some games than others I don't know what GW2 has to do with it.

4 warriors of light is probably one of the prettiest DS games I've seen.
If you have to dig up some negativity about it then I guess it's directed towards SE for working him overtime and not letting to focus fully on one project back when he was doing drawings for XIV's world. I wish I could link to the images of landmark designs in the Famitsu magazine they're quite spectacular.
