It's just about balancing more, and like Snix said in a post I saw earlier today, Bungie is trying to make everybody want to use all of the weapons, no more whoring the sword around like in H2, the Magnum isn't terrible like in H2 and not overpowered like in H1, rockets can't lock on, Banshees can't look directly down (referencing to the BS on Ascension in H2), and more that I just don't feel like posting. I love H3 so far, honestly I love the magnum.
last night when i was using the sword, i was so glad that it was balanced! i stopped using it and just whipped out my pistol and popped people in the heads
I honestly don't remember my post above lol, but yeah, like I was saying, even though its all balanced out, the sword and magnum probably will change along with all the other weapons and gametypes... its a beta, and the sword especially is part of a beta we weren't supposed to even use... so we can't complain...
