As a dedicated Obsidian Mind Voidwalker I can without a doubt say I'll go toe to toe with a Nightstalker on kills and orb generation and most of the time, beat them. Don't get me wrong I absolutely adore running with a Nightstalker they're amazing in PVE. But I can Novabomb, make 7 orbs and I'm ready to Novabomb again. Shot placement is crucial but with Shatter, Annihilate and Bloom dear God I'm a monstrosity especially in the Undying Mind strike. Hate Precursors? Get a Voidwalker on your team you're welcome. I love the friendly competition with Nightstalkers to out make Orbs and if you have a Defender on your team as well get read for the best strike running team of your life. This is my favorite way to run Three of Coins strikes we're always supercharged. Void classes are amazing orb producers. I'm good with my Voidwalker, but I've seen plenty of excellent Nightstalkers too. Be wise with super usage and you'll never run out of super it's that simple. Side note, the Obsidian Mind Voidwalker is my favorite class. In the course of one strike I can activate my super almost 20 times. It's a thing of beauty.
