This thread gave me an undeniable urge to load up BL1, which I haven't done for ages. I never did finish Claptrap Revolution.
On topic, I'm still in the first quarter of BL2 and I hope the Malevolent Stingers are back. If not, I want them. I used my level 49 purple HX 4 more than all of the legendaries I found farming the armory and elsewhere the first time 'round.
No stinger in BL2 which sucks because they were awesome. The SMGs in this game fire so sloooooooooow.
