This is my opinion Vex Mythoclast and Tarrabah both should receive buffs since they are the only solar primary exotics which have no synergy with solar (Hierarchy of Needs recently got buffed to further fit it’s niche and because of that, doesn’t need solar synergy). There are little reasons to use these two exotics over other primary weapons such as Devil’s Ruin, Sunshot or Polaris Lance. For Vex Mythoclast, I would rework the current catalyst’s bonuses into the weapon’s intrinsic perk, and change the catalyst to this: -Defeating a target while in full-auto modes triggers an explosion which scorches nearby targets (Incandescent). While in Linear Fusion mode, landing precision hits triggers an Ignition. For Tarrabah, since the secondary perk is about sustained damage to extend the duration of Ravenous Beast, I personally think that a catalyst is added which grants the weapon Burning Ambition (Dealing sustained damage scorches the target).
