I don't get what the ammo complaint is.. Maybe I just got a good kinetic exotic. I use an elemental assault rifle, that chain gun exotic, and the grande launcher. Yes heavy ammo is scarce and I'm sure they will fix that. Head shots with the chain gun exotic do crazy damage to him and since its special ammo, you get a decent amount of pickups. Shout I mean the sub machine gun does amazing damage if you can get close. Me and my teams take him out pretty quickly. And the bullet sponge argument.. He is one of the most dynamic strike bosses they have given us. If you wanna see bullet sponge go fight nexus mind again.
