I'm curious about the weapon customization/upgrade system. How in-depth will we actually be able to go with this system? If I buy a baseline assault rifle, am I able to evolve it enough that it barely resembles the original model? Will I see a lot of other players using guns that resemble mine too much for it to be unique? Will there be different ammunition types to choose from? Also, how do Exotic Weapons (such as the Thorn and Thunderlord) differ from customized weapons? Are they more limited in what you can upgrade?
