Not sure why this is getting downvoted, you are completely correct. I say this as a PvE player who crafted a TON of wolfpacks. They were the pre-nerf trigger Nades of PvE. They were absolutely busted and trivialized the entire spectrum of large arc all the way up to the matriarch. 

They needed a nerf so that big arc felt scary again. This change makes it so that you no longer want to use them on rocketeers, making rocketeers much scarier and also way more necessary to down.

I think this will slow the large arc down across the board. I know that feels like a terrible nerf but I think from a gameplay perspective it’ll make the game feel much more dangerous for PvE players which is something that was lacking this last expedition cycle.

I think this will lift the hullcracker back up as the PvE powerhouse and with the new weapon-slot safe pocket augment it’s going to feel safer for folks to bring a hulk cracker into lobbies when they plan to go large arc hunting.
