Okay, these are the two biggest issues I have with DUST weapons:

First, the drop-suits are a bit frustrating in terms of weapons loud-out. I'm primarily a sniper, but when I run out of rounds for the rifle, I either have to make a mad dash for the sometimes-distant Supply Depot (and hope that I won't have to use my mostly-ineffective Scrambler Pistol to defend myself), or suicide to switch my focus (which loses my team a clone).

A second Light Weapon slot would be nice; that way, I can defend myself while I'm heading for my sniper nest, or for when I just want to jump into the fray without suicide-running just so I can get into a different suit.

The second issue has to do with the targeting cone of most of the Light weapons. After playing for a while and checking my hit locations, it seems that the assault rifles and SMGs in particular require that the player directly target the enemy's 'center mass' to hit anything. In my opinion, they could be a little more forgiving.

Anyhow, those are the only major weapons issues I currently have....
