I'm a Warlock and can honestly admit a Storm Caller lock dies pretty easily. Shotgun/Melee combo does the trick or Headshot from a High Impact Sniper. Problem Solved.

You must be using the Khostov. I slaughter and get slaughtered as a Stormcaller, it's the tradeoff. It's a glass cannon, it hurts but gets hurt easy. I can wipe out a team, sure, mainly if they're all dumb enough to cluster together for my Landfall. Stormcaller isn't B.S. by any sense of the word, it has barely any damage resistance, most of them die mid super.
