IMO the only issue is combat goes by too quickly. Often when groups of 5 or more members of opposite teams meat one team is completely eliminated in less then a minute, instead of an intense firefight starting.
Basically , I feel rifle should be less "Accessible". The red dot on the Iron sights makes aiming a bit too obvious, and once someone has played maybe 10 games they become proficient with the rifle.
In the older days the old iron sights were crap, but still pinpoint. Basically Ben should remove the red dot on the iron sights, but still leave accuracy the same, so it increases the amount of time it takes for a new player to get accustomed to the iron sights, which would make the semi more of a semi, leaving the door open for a sniper rifle (Which I in no way support, as everyone would chose it)
