I learned a way how to do the Crucible bit for the Last Word. Shards of Galanor gauntlets (that I got during Festival of the Lost) has a perk that regenerates Blade Barrage faster. So you have those on and Blade Barrage, then go into Mayhem because after every successful kill, your super is fully charged.
Oh, my Shards almost never come off! They’re my favorite hunter exotic, but my percentage still went down trying that in mayhem. XD;
Though I swear, I’m tempted to go into that mode with tether and Orpheus Rig just to be a spiteful little bitch and shut everyone down. ???
