What happens when you run out of nades? Do you just sit there and think, "Oh crap, no nades, what do I do!?!? No, you just shoot him. My point is improvisation. In 1v1 sword duels, you going to need to be faster than your opponent. Anyways, think of it as another challenge. Or, if you want, redo the map, with higher walls and a higher roof, if you want. I'm fine with that. I simply realized there is not a single map on Halo that is optimized for 2 person sword duels.
