Sunbreaker was nerfed because it was good at everything, Trials, Iron Banner, etc. On crucible radio, Sage said you could randomly throw a hammer and get murder three players. Stormcaller is different. It can compete, but players switch subclasses on different games modes for specifc reasons. Trials is mostly Sunsingers because burning firebolt grenades and fireborn. Voidwalker makes a portion of 6v6 game types because blink shotgunning is still popular. Most likely Bungie will slightly buff/nerf depending if they think if it is too good/bad on pacific encounters. http://guardian.gg/en This website does show that the subclass is at a good spot.
