Titans whined a lot more, anyway. The super received an unnecessary nerf not due to titans, but Bungie. They didn't know what to do, so instead of make supers good (Voidwalker will always be a terrible subclass because they missed the chance on HoW meta) they just flat out destroyed arc blade. Stormcaller isn't OP now. Arc blade one shots at close range, stormcaller three shots at medium range. Think of it as a free chaining lightning mid range thunderlord for 20 seconds.
