You can get some cool titles and achievements by simply having the weapon, armor and tacticals in your inventory. You have to get most of them yourself as they are bind on pickup however a few are tradable. We got full sets of each which we've used to help a lot of people get the achievements over the past year.
The plan is easy. I'll be standing next to the inner ring guild bank on Fleet. If you want the achievements then come to me and I'll help you out; first come, first served.
