I only use shoty for defense. Mainly mid to long range is where I play. Still get 2 shot killed my lunas. Kills me even faster than even my kill clip and even at range.

Luna’s is a 3 tap. Only on rare occasions does it 2 tap

Not rare enough. That's kinda the whole argument against it.

What? Lol. I have Luna’s and that maybe happens once every 12 games. You have to hit someone twice then switch targets in the middle of the gunfight to 2 tap someone else then switch back to finish off the other guy. By that time you’re dead unless you’re in a well of radiance. And if you use well of radiance as a warlock in PvP then you’re stupid for using the wrong subclass.

Also noteworthy that the 2 tap is only possible against Guardians of 2 or less resilience. It's quite rare.

That's completely false. As long as you're within full damage range for Luna(and similarly, Not Forgotten), Resilience literally means nothing if they proc the perk on you, or proc if off of someone else and use it on you afterwards. I'd know as someone who's had NF for quite some time now, though I definitely wasn't among the first few who got it(as I wasn't playing Comp. at the start of Forsaken). That's why Resilience is the least specc'd into stat in high-level Comp. in most cases. The only things it'll help you deal with are Bygones(by an extra headshot for optimal TTK), Telesto(by an extra bolt to kill you), and pellet-based Shotguns on rare occasion because of how inconsistent they are. So in most scenarios, it's better to just spec into Mobility/Recovery or your cooldowns.
