but the dmr literally has the same mechanics as the pistol. its a single shot headshot capable weapon. sure the shot interval and reload speeds are a bit different, but if we had a rocket launcher that was exactly the same in function except for shot interval and reload speed it would be pretty clearly redundant. the DMR is already much too similar to the carbine for my liking. (which wasn't an issue in reach since there was no carbine)There are reasons to use those weapons. Are you genuinely unsure or just don't think the reasons are good enough? Reason I ask is because I know you think of these things critically, so I know you can name strengths of the BR and DMR over the Pistol.
the pistol in halo 1 was the ONLY non sniper long range headshot capable weapon. when its one of many such weapons it's got to fulfill a different role. its can't have basically the same utility as the BR when the BR already exists.
basically the BR would need to be vastly different in function and the DMR and Carbine would need to be gone before it would make sense for the pistol to have just as deep a clip as our established stable of second level precision weapons.
I understand that you just like how the pistol feels and its specific tuning, but I care about things feeling like they have a purpose. in CE the pistol was great, but it also had a clear purity of purpose. lifting that same exact weapon into halo 2 or 3 (WITHOUT changing any other precision weapons) would not. it would feel messy and hacked together thoughtlessly. that's not what i look for in game design.
