i dont care if all of my old gear becomes worthless in TTK, im keeping my jacknife/graverobber and CE armor, Zombie apocalypse and venation III (as well as other select favorite gear amongst my titan/warlock). i SEVERELY regretted dismantling my ghostwalker gloves/feet from vanilla into TDB, and im not making the same mistake again. yeah, my vault is currently jam-packed with gear (especially the weapons), but in the end theirs alot of guns in there i dont ever use, so ill be dismantling as i go accordingly, and im sure their will be new weapons to love in TTK as well, but im not letting go of some classics. ever. keep your select personal favorite set, as it just might very well make a comeback like E. light did for HoW.
