I hear ya...but I think a 30 round clip defeats the purpose of the String of Curses upgrade (auto reload and damage boost after every kill). Now that I have this crucial upgrade, I actually really like using it for PvE. But this is only because 5 burst rounds is usually enough to kill a low to mid level enemy, giving me the opportunity to get an auto reload after each kill.
But, when it comes to PvP, 5 burst shots is just not enough to kill a Guardian, so I NEVER get an auto reload unless I steal a kill. But, I do consistently get close. SO, I really think just one more burst shot would be enough to make this gun viable for PvP. And, I think it would be sweet if Bungie's took advantage of the 18 round clip and the 3 digit ammo display to spell out "666" (6+6+6=18) in order to further tie this gun back to Toland the Shattered's lore (who was known for delving heavily into dark magic or some sorts).
Thank you for posting, let's hope Bungie is listening!
