Is it worth the gambit grind?
No, hip firing even with opening shot and a free hand grip is still inaccurate. The draw time after a crit hit is so satisfying. But if you miss the first shot you'll notice how slow the default draw speed is. In pvp garbage. Hit that first hip fire shot or you're dead. In pve weirdly enough Vex are hard to crit with it. Scorn with the little shields is annoying AF. Only for boss damage I like it. You just keep hitting that crit spot over and over. Feels good. On spider tanks it's the most fun to use. But overall in both pve and pvp there are way better options for the energy slot. I say just play gambit. Eventually you'll get it and have 7 free enhancement cores.
