How is it functional when a lot of the fonts on the item stats / item detail overlays are too small for me to see without straining my eyes, leaning over my desk, etc?
A lot of people here haven't considered one thing: Just because the UI "looks fine" to a lot of people, doesn't mean it's "just fine" for everyone.
There's a difference between a website that is made with bright colors with lots of Photoshop "glow" filters on the text to look cool, with smaller-than-usual fonts, and a website that uses all the available screen real estate to display information and navigation with large fonts, balanced whitespace, and make it accessible to everyone.
The difference with those two scenarios is that one looks cool and one is accessible to nearly everyone.
You can't *please* everyone, sure. But if the UI is hard to read for a lot of people, which it is if you read the forums, then it's not a great UI. I can play Skyrim, Witcher 2, and Starcraft 2, all of which need to present a lot of info on screen, without straining my eyes or getting a headache or neckache. But not SWTOR. Which is my assertion for why the UI sucks *for some people* and is not *as good* as the UIs for many other games.
