Wow... I would've never considered 2mm action low by any means. Medium at best, and I'd say so because it's "factory spec". I guess we all indeed see things differently.
Personally, for me, I kinda hate the idea of having an expensive guitar with high action. I played too many cheapie guitars that needed fret jobs bad where the strings had to be super high up, or else I'd get dead spots and buzzing like crazy. So in my mind, feeling a guitar with high action immediately goes my brain go "this feels cheap". JMO.
Luckily, Gibsons are plek'd nowadays, so they tend to be easy to set up with the low(ish?) action that I like with minimal buzz. I still think 2mm is way too much for E Standard, personally. I didn't realized people actually kept factory setups. Many of my friends set their guitars up with lower action than I do. Then again, I do play in Drop C and I play hard.
