Yeah HH is only good against 1 target at a time, anyone halfway serious about pvp travels in groups. You don't have time to knock down a guy 15 times when people are shooting at you and even with mega powerfist you're looking at like 40 damage a punch. That's roughly 10 seconds to kill 1 player when most bursters can kill you in 3. On top of this crits are heavily diminished despite HH pretty much requiring fast shot to be effective. I don't see why there is so much resistance to variety of combat styles, it's like you guys want to be bored.
BTW avv, low pe chars aren't pvp chars, if anything they'd be hth so sneak isn't really an issue. Even if a sneak killed one guy he'd get killed right after and even if so, sneak chars shouldn't be able to kill? Sneak builds are the most demanding builds and they don't perform like they should. Sneak hth isn't even a thing in this game, no one has this build because the weapons suck.
