My main is a warlock, I prefer void walker for nearly anything, except where I need the Rez to help my team, if I run the relic in vog I use Rez so I can solo gatekeeper portals and in case of glitches it prevents wipes. For the entirety of the crota raid I use void walker, being able to blink away with the sword is nice and dying in that case spawns an oversoul anyways. You can easily tell if a person is skilled or unskilled by other means that what they use as a class setup, it's just an ignorant statement to assume anyone who uses Rez is a bad player.
