Creating a Dual Blader. 2 questions

What's with everyone thinking Dual Bladers get nerfed? What a common misconception.

It's given fact that it's an illusion that they're nerfed since everyone else got buffed, but they got buffed slightly too to put them on balance with everyone else.

The only nerfs Dual Bladers got were to Triple Stab, Fatal Blow, and Chains of Hell which in turn got an additional critical activation probability. Every other skill either stayed the same %/s or got stronger, and since their base damage was increased anyways, there's hardly a difference to the already overpowered strength of these skills to begin with.
