I'm wondering if anyone knows if there's an alternate way get to exotic catalysts for the faction-specific weapons (sunshot, graviton lance, riskrunner). Graviton Lance was by far one of my most favorite guns to play with but I've stopped using it in favor of other weapons that I can actually masterwork. I've only been playing Destiny for four months tops but I've been making up for lost time (584 PL). Factions haven't been going since before I started playing so I haven't even had a chance to get them. I wanna melt Taken with my voidypewpew at max level AND get orbs of lert, plz.
