Try and think of it as that the enemy has adapted to counter it somehow, I dunno whatever helps you sleep at night! They nerfed Suros, Vex, Hawkmoon, TLW, Icebreaker, Thorn, Gjallarhorn, Truth I could go on (literally every single gun in vanilla D2!), so of course they would eventually get to this beast that's not even an exotic. I only got it a couple of months ago and it's been fun, but this had been on the cards for a while. I get why you're mad though.
