The Laterano faction seems to scale the fastest and the hardest if you can get it going, which I suspect is because it actively scales with itself
It also synergizes quite well with Agile, because that scales with Silence alone, just need a second activator
See most of the operators grant Laterano scaling when they or another Laterano operator use ammunition... and the bonus is that they have more ammo to spend. Which I believe is exponential limited only by the amount of flesh that your opponents have to shoot at.
I haven't got any of the other factions above fivd hundred, nevermind the six hundred here.
Even trying with Clementia on Aegir didn't yield quite matching results:
The Kjerag faction bonus kind of takes the wind out of its own sails via the 30+ second cold debuff. Pramanix and Silverash as the primary scalers both procc when something gets frozen, not for the amount of enemies frozen in range, or for how long they stay frozen. I could just be bad, but I've yet to get more impressive numbers:
