1) The bars are too small and too close together to differentiate easily.
2) The bars need to be close to different points of interest - the Adrenaline Bar near your character so it is in eyeshot when following your toon in combat, the Encumbrance near your backpack/inventory so it is in eyeshot when filling bags, the Food & Drink near where you are crafting, so that you can keep an eye on levels. Just these 3 are enough to see that they are suited to different locations, so putting all the bars in one place cannot work. The locations weren't ideal before, but at least they were aproximately where they needed to be, either left of centre, or right of centre, and split up enough to be able to differentiate easily.
They need to be bigger
They need to be separate
I can't see why they were even changed to be honest.
