My only complaint about it is the ridiculous wandering time. If I can be killed on the enemy side of the map and then respawn and get killed by it again because he's made it into the spawn still charged, that's a bit OP. I hope when Bungie does one of their weekends where they play against the community that they run into a whole team of stormcallers. That's the only thing I'd fix. Decrease the amount of time you can cruise around the map.
