I'm not listing numbers because CCP already has them and if the community really needs them I suggest looking them up personally.

Combat Rifle versus Burst Assault Rifle:
Combat Rifle has higher damage rounds, faster rate of fire, longer range, lower resource costs and lower price.

Rail Rifle versus Breach Assault Rifle:
Rail Rifle has higher damage rounds, faster rate of fire, (much) longer range and lower price. Resource costs are higher though.

Scrambler Rifle versus Tactical Assault Rifle:
Scrambler Rifle has higher damage rounds, faster rate of fire, longer range, lower price and the ability to charge for three times the damage. Resource costs are much higher however.

So, if all the races have their primary variant and the other races have designs that emulate that... Why is it that the Assault Rifle, being the primary weapon of the Gallente, has such similar DPS values to the emulators that it's literally single digit differences? The range is the shortest and yet even the Rail Rifle (once charged) overshadows it in the damage factor.

If they're meant to emulate the Assault Rifle than why is it that it's being outclassed?

Honestly, given that they have lower ranges, -all- the Assault Rifles should have higher damage dealing capability than the other rifles because that's what they were designed for. Close range, high damage capability. That's not what we're seeing here and when the Kaalakiota Assault Rail Rifle has replaced the Duvolle Assault Rifle as my primary armory, despite having such intensive skill investment into the Duvolle, there's something strange going on.
