Yeah, hand-cannons are in a pretty shitty spot. I just ran through the "Mountaintop" quest to finally unlock the weekly Shaxx bounties and while I got enough kills with Hawkmoon in each match, it really highlighted how abysmal their performance is right now. I had an Ill Will with amazing range perks a while back and it was still pretty good, but I shit-canned it because I never used hand-cannons, so I had to rely on Hawkmoon. Anyway, yeah, they are just about worthless with shots missing for no reason. I took my took, took well-aimed shots, fired slowly, and still just couldn't really hit shit.
As for Supremacy, AKA "Shotguns Only", not a big fan, but it's not as bad as I had imagined it would be. I went into Rift yesterday to do an old questline objective and we ended up going against an entire trials flawless team... they didn't pick up the spark, but camped it, and basically farmed us for kills for the entire match. Kind of shitty if you were just starting to play and that was your Rift experience. I also forgot how fucking long those Rift matches took to complete, holy hell!
