It would have been if it had been missing. It's not missing, so in a sense we are both arguing on an old assumption. Let's not forget that the inventory, shortcuts and UI, which are only just barely usable, ARE without a doubt the fault of console design though.
I have a more nuanced view: for example the skills GUI is beautiful, the way the skill trees resemble constellations. It's also about as much use as a chocolate teapot from a user-friendly POV, I'd much rather have a more traditional skills / character screen (I'm sure the current set up looks great on a widescreen TV). The port to PC's controls are hideous.
This isn't because console gamers are dumb or less sophisticated (although I guess some might be, what else explains the popularity of Zumba party etc) it's because the platforms are different and PC is way more marginal.
PCs days ain't numbered, but we are niche and we are less important than the console version. Just the way it is.
