I spend 85% of my time playing SWTOR either Crafting, Gathering or on the GTN (And I play quite a bit)
I can't put my finger on all the changes that were made but I like the feel of it. Here are the positive changes I can notice (I haven't read any patch details)
Changes I've noticed:
Smaller and better positioned stack sizes.
This makes it easier to read stacks in the 100's or 1,000's. Also it looks like some sort of dark outer-glow was added to better separate it from items with light backgrounds (like some silks). UI window alignment layout appears tighter
And better positioned as well. I hope this will prevent "clicking through" the inventory and grabbing something on a sidebar. Gradients on item borders.
Hmm not sure about this one.. There's probably a reason for this change, I just haven't come across it's benefits yet. Makes it a little more difficult to quickly pick items with similar pictures but different color grades.
For instance: Nerve-Damaging Chemical & Brocart Filaments.
Strange though, I only see the gradients on one of my characters inventory and not the other. Cooldown Timer Text
Love this no complaints so far.
Will post additional feedback as I notice things.
