I've had gjallahorn for about 7 months and tbh I am getting a bit bored with it. I equip different guns when helping others through strikes and missions but feel I'm expected to equip it in raids poe etc. I would be more upset if they simply weren't available but if I can still use them in crucible etc then I'm ok with it. I think they made the original guns too powerful and therefore new guns in the dlcs have struggled to compete. They can't simply make each new gun better as you'd have power creep. They also did this with dark below ( for vault weapons at least) so I was expecting it.
