Came in expecting maths. Such disappoint.

The max DPS of a CR is below 430...
And any good scrambler rifle user easily gets above the 500 DPS. And even if it was 475DPS, it's still above any other rifle in the game while having a long range. To me that's the problem. The ScR completely breaks the range vs DPS chart and it has nearly no kick and dispersion (which is perfectly normal for a laser weapon, but added to all the other advantages it's too much).

Anyway, if as you say the ScR can't get above 6 shots per second, you shouldn't mind if the RoF is dropped down to 420RPM (7 shots per second)

When you take into account the minimal burst delay of the CR the DPS is about 430 (I wrote the exact number in another thread but I'm too lazy to find it). But I do agree about reaching that max DPS is easier with the CR.
Reducing the RoF to 525 would already be a good start and may be enough as we indeed don't have a clock in the finger.

It is balanced in a way that doesn't make too much sense for a FPS. The notion is that the overheat mechanic keeps it from being too powerful despite having some incredibly "efficient" (Rattati's word) stats for damage, range, a charge shot mechanic, and an increases headshot multiplier. "We averaged it all out and it turns out that the DPS is about the same as most other weapons" is my guess on how it was balanced. Obviously, in an MMO where play is really quite slow such as EVE, that works relatively fine. For DUST, where TTK is about 1-2 seconds, having a high front peak means potentially being able to factor eliminate someone before the overheat mechanic happens meaning that the balancing factor never comes into play. IE, "If Rogues had every cooldown for every fight they would be absurdly overpowered" and then Arena happened.

Is it too powerful? I dunno. I will say this: it is a weapon that is highly skewed towards shields (+20/-20) and is still used quite heavily despite the fact that Armor is generally superior to Shields or is at least used more extensively than Shields. When it was the Bumblebee of death, Explosives and Grenades disappeared in favor of Flux Grenades. The weapon is at least good enough to still be used in an environment that doesn't fully support it, which is nice, but I am still not sure if it is too good.

Max RoF is around 850. Your numbers mean the burst delay is .01 second, that just doesn't make sense. Anymay, find me somebody able to press the trigger exactly .01 second after the third bullet has been fired. And even if it was the case, a guy able to have a such perfect timing should easily reach 750DPS with a scrambler

I think he was pointing more to its kills + efficiency becoming the highest. In theory a bunch of scrubs flocking too it would make sure that it stops even being considered as "slightly op" as he said in another post.
