In preparation for Trials of Osiris, I've been playing a crap load more PvP than I used to. To allow for more flexibility in load outs, I'm wondering what are the top options for a Legendary Primary for PvP purposes? I have some of the top Exotic options such as the Vex, The Last Word, Mida Multi Tool, and, to a lesser extent, Suros Regime. But I'd like to add some flexibility for Heavy use. I currently have Gjallarhorn and Thunderlord as my Exotic heavy options
