Item Drops and Finds Version 2 - Post BB

So why is their additional options better than PvP's pocket?

I'm not really quite sure what you mean, but, I'll try to answer. I'm not sure you can even get additional options on pocket items, other than the ES Square. There's apparently a system of icons, in the top right corner of item images in the description window, that determine whether or not an item can be flamed or not, I think there's a dot, and a flame with an empty dot in the middle, and apparently they vary in opacity, and depending on the symbol you may or may not be able to flame the item, I don't know very much about it. But anyway, since most items from special shops, like event shops, or basically any shop where items are bought for a currency other than mesos, they automatically have additional options, this might extend to regular equip shops too, but I dunno, I can't remember buying anything recently.

Anyway, I guess what I'm trying to say is, I don't even know if you can get additional options on PvP pockets, because I'm pretty sure pocket items are one of the excluded categories, along with, I think, badges, medals, and secondary weapons/shields.
