My experience with handgun HS since the reload time buff at the start of the Beta is very positive so far I have to say. It feels pretty good with Thrill of the Hunt as is. Comparing HS to other ranged classes, BH has 15% built in as a passive, and now a talent that lets him bypass reloading altogether. Then there’s RV who also has reload speed baked in with a passive, and has the whopping +35% from firing fury - though this doesn’t help handgun builds any.
But then you also have to factor in HS’s Ult. I don’t know what the actual % is, but I’d definitely say that he uses handgun better than RV reload speed wise with a decent headshot rate thanks to thrill of the hunt + Ult. He already does mean work even to Cata Chaos pats with handgun + Ult + a few headshots.
I’d be pretty fine with him getting a reload speed buff through talents or passives, but - at least in the case of a passive buff - it might need to come with a reload speed nerf for his Ult to stop it getting silly. Ideally he’d have the same reload speed overall in Ult, but more compared to now when he’s not in Ult.
