What did you think about stormcaller and sunbreaker?

I only tried stormcaller, because I only got to play one match, sunbreakers hammers have one hit splash damage, stormcaller was a pretty weak super but could destroy enemie teams when they are close together, it takes time to kill. But there was this one gunslinger killing 3 people every super shutting us down. The Nightstalker wasnt very effective, even though the arrow can kill someone it isnt effective to kill everyone it tags, you can still easily kill people while binded, so overall... Titans are going to dominate due to their bladedancing/golden gunning.

Ok. Only crucible right? I'm interested in how they work out in pve. I heard that the stormcaller warlock is pretty weak. Can you confirm that?
