i don't expect it to be big, i would welcome it to be complex though.
the augment system of ffxi was extremely stupid. I dunno who invented this. I hated it And due to the many bad stats and rarely decent results : i know someone tho got -2sec on the 2 hr ability on an item... how great is that lmfao.
I think it was just a gear-sink of some sort. Pretty stupid idea though.

I think it will be a bit more then just equipping it on items but im not sure what it will be like and the speculations go way too far for me ... i hope ill see a positive surprise that is all.
