I don't have an issue with stormcallers. I think they are fine as is. As a HoS user, it is op in pvp. It's pretty useful in pve and has saved myself and my fire team more then once. If they could maybe make it a two hammer kill for pvp and leave it alone for pve, I think it would be reasonable. I would still be able to wipe a team out as long as I use it properly.
