Its hardly a 2 OHKO and from there you can either switch out or wreak havoc by setting more hazards or crippling Heracross XD.
You're right Goth cannot switch in that freely to defensive pivots if it were the SPECS variant - I'm not at that much of a liberty to say if it is popular or not - assuming of course they are faster than her (but given that Goth is better capitalizing off slower mons I generally stick to those pivots). But trick scarf variants are more defensively built to choice lock their target without much fear, meaning its the better way to screw over faster mons. Either way she is set she gets her job done with ease, neutering or eliminating walls or pivots. That opens the way for her team mates to do their business in peace.
Whoops I was assuming more speed. Well Scarf has its own problems as well. I don't know the standard either, I'm using Scarf now built to outspeed + nature 95s so I can retain Modest power and some bulk investment, and it's still (obviously) kind of slow. The sheer power is missing as well, as well as a coverage spot used for trick. I'm not saying Goth isn't effective, I'm not saying it isn't dangerous, just not unfair. It can do a lot, but not all of it at once. I'm using Honchkrow on the same team, and imo it's a scarier trapper with Moxie Pursuit and a sweeping opportunity. It's hard to survive a 80 STAB from krow, and that goes for Sucker Punch and Pursuit.
