I have all 3 Exotic Swords on my XBOX account and have started all 3 quest lines on my PS4 accounts. I feel all three are amazing. I find myself swapping between all three constantly depending on the situations I'm in. Bolt Caster: Range Conflict/PvP Dark Drinker: Crowd Control Raze-Lighter: The Giant Slayer/Court of Oryx Honestly, I don't know if I can pick a favorite. I do find myself using certain ones more on specific characters (Titan: RL, Warlock: BC, Hunter: DD) but I swap between them all the time. Like in the KF raid, I was on add duty for Daughters and used Dark Drinker to clear the adds, but then quickly swap to bolt caster for attacking the daughters and then used Raze-Lighter for Oryx part against Light-Eater Ogres, back to Bolt Caster for 'Echo'. Overall though, I feel Bolt Caster is the most useful as I like to keep some distance from enemies. So if I could only have one it would probably be Bolt Caster but I've grown quite fond of the hard hitting power of Raze-Lighter. What about you? Also how did you approach doing the quests? I regret having my Hunter do Dark Drinker even with my farming technique I used to build up my super progress (hint: We've woken the Hive). On my PS4, I'm having my Hunter do Raze-Lighter quest and my Warlock do the Dark Drinker.
