The general consensus is that the Arachnid Sensorium perk is underwhelming when used outside of Crucible and outclassed when compared to the other Hunter helmets. Most suggestions call for adding critical damage to the shots in order to buff the perk. I'm sure this comes as no surprise. Gunslingers have been begging for Golden Gun to do critical damage forever now, and I'm no different! Okay, no, I'm a little different. I believe in the power of shamelessness and diplomacy for the good of all.
Instead of doing straight critical damage, the Arachnid Sensorium perk should allow for critical damage on [i]successive shots[/i] while ADS. The possibility of x2 critical shots will increase the ATS/Arachnid's utility while maintaining the theme of "skill" or "precision" in Gunslinger encounters that I believe the devs were trying to bring into this exotic.
