I try to use just about everything. When I play crucible with my clan, we usually change our weapons up every game and take turns calling the new loadout. It's a good thing I don't care about kd, because last night my No Land Beyond/fusion/Legendary sword hilt (no ammo) combo was brutal... I'm pretty sure most of my kills came from melee and grenades. That said, however, since it's IB and we want to win, I'll probably go for TLW/Doctrine of Passing/Mida; 1000 YS/Conspiracy; Quillim's/Truth. Pretty standard stuff.
