I have 400+ more kills with the BR than DMR..

…But the DMR is apparently my favorite weapon.

How does this work? Is it by time with the weapon? Do spartan ops kills count? I just don’t get it.

I think it may calculate what you used across Campaign and Spartan Ops as well.

Yes it does count every kills, including Campaign, Spartan Ops and War Games. (I’m not sure about Costum Games.)

The railgun is my favorite weapon(aside from the Reach grenade launcher), yet it is not my favorite weapon because it’s not the one I use most. it should be ‘most-used weapon’.

Are you afraid what we might think of you? Relax pal, keep using the BR I love it now too even though I started the first few weeks the game came out with the DMR.
