Please double check your stat differences under attributes. While mousing over the slots, some gear does not scale up; however, the scaling is still in effect.
Goggles still give 5 stam, 5 hit despite reading 4 stam 4 hit
MM gives 17/5 despite reading 14/4
Fotl still gives 10/6 despite reading 8/5
etc etc
Some do appear to still read the upscaled numbers such as Cloak of stam and BoAs,
I checked all of my gear on my current toon. Even though most of the items don't show scaling when moused over, they are all still giving the correct (upscaled) stats while in BGs.
