I'm typically not one to be super critical of changes that are fundamentally positive for the game, but I've gotta say - those new accessory icons are absolutely horrid to look at.
I understand the need to revamp the visuals to better relay the actual positions, and while I'm not too happy with the full body in the icon I could live with it. But some of them just radiate that "graphic design is my passion" energym.
The head slots are mostly fine, but the armor ones are just awful.
Some constructive criticism:
The "aura" ticket should remain an outline of the body. Filling in just part of the background looks super tacky.
The "back" accessory should make an outline of the chest, and not be filled in.
The "front" accessory should outline the chest, and be filled in.
The "rear" accessories should outline the waist, and be filled in.
These adjustments would bring them more in line with the existing icons. You can also make the body icon a bit larger so that it occupies more room on the icon now that the highlights are on the body rather than most of them being behind it. The rear and back really need to be changed as they're practically the same - this is the same issue the front and back armor icons had in the past and instead of fixing them we've just moved the problem somewhere else.
Though I agree the aura is definitely a stinker I think most of these new ones are fine. Maybe for the front ones they could be outlined and filled but for the back and rear accessories I think what's there now would be much clearer to understand than what you suggest. If anything, I don't get why you'd suggest the rear be filled in. Are you not using the fill to suggest a frontal area? I do agree on making the overall body icon take more space.
The old icons would be pretty much impossible to rework to clearly suggest what's being affected. I totally get why this change had to happen.
