I get the idea is to highlight gunplay and all that. The special ammo gimmick is interesting. But from my experience, the mode mainly just highlights how strong hand cannons are in the game since their usual TTK is unaffected in most cases while everything else feels weaker. Didn't try scout rifles or bows, but I imagine they're decent for the same reasons. I think if you were to use a different weapon type than those, you would just be putting yourself at a disadvantage and with the special ammo gimmick, you'd probably find yourself more-often-than-not getting rolled. Personally, I don't see this mode taking off the way that it is. You might be on to something with the special ammo though, Bungie.
