The following numbers represent how long it takes each weapon to output 600 HP damage on a level field (no efficacy bonuses) with the exception of the ACR.

ACR 1.36363636 seconds (need more info on the vanilla CR in order to calculate - specifically "burst delay interval) as well with the projectile type weapons this number will be further reduced by 5% due to it being the only weapon type with an unbalanced damage efficacy swing (i.e. 95%/110%). This number then works out to-á1.29545454 seconds.

AR-á1.28342246 seconds.

RR 1.2892519-áseconds.

The SR is a bit tricky as it is a simi-auto weapon. Many sources would say that 660 r/m is pushing the limit of human capability, and that while griping a gun handle (equivalent DS3 grip) achievable RoF is around 480.

This is a video of a world record being set for revolver:

If you subtract the time it took him to reload, the RoF works out to around 8 trigger pulls a second (his world record is actually higher than 8 by several desimal points). This will work out to around 480 r/m. So that is the RoF we will use.

SR:-á0.9469697 seconds.

So as you can see there is a problem. There is one weapon that is far superior to all of the others: the scrambler rifle, by an obscenely large margin. I feel like this can be easily felt in the field.

Conclusion: the SR needs to have its damage per shot reduced in order to bring it in line with the other weapons.

Also

The difference between the payload output of the AR and CR/RR is very-ánegligible.-áIf the AR is supposed to be the king of CQC then I would recommend increasing the AR's RoF to around 800 r/m.

At 800 r/m this would bring the AR's payload delivery to-á1.20320856 thus adequately making up for what it looses in range.

This is for everyone's consideration, but I hope that CCP will pay particular close attention to this thread.

If anyone is interested in knowing the math I used to calculate these numbers just ask (you too CCP) just ask and I will post the equations.

{edit>>> also, I would recomend that the max possible RoF for the SR be reduced to around 510 r/m, in order to discourage the use of mod controllers. The RoF should still be a little high to reward those capable of achieving such an output.

Haters Gona hate.

I took into account everything that was necessary. You can prove me wrong by presenting relevant factors that Were not in the OP.

"- SCR and AR have 10% penality on Armor. Which means it's (almost) a 10% permanent nerf to all ennemies.
-CR and RR have 10% BONUS which means it's (almost) a free complex damager against EVERYBODY."

Didn't make it past that, since it is very obvious that you don't have a clue what you are talking about. Also, if you can't understand the relevance of the factors that were and were not taken into account, I cannot help you. Try reading the whole thread or at the very top of this page there was an excellent post concerning this.
