SK's have been nerfed, that is true, but if you are using PVE build, then you use self destruct wave.
When you increase it to lvl 2 or 3, you can use power RP increase and critic 9k or more with base dmg of 3-4k(based on gloves you wear), or higher.
This is because mobs are a bit more tank-ish than it use to be and they deal more dmg but still like I said, if you use vilent slice at least lvl 2 for reduce CD and self destruct wave, it shouldn't be problem, you would farm way better.
How much I saw, only skill that has been nerfed is Bold Strike, base dmg is lower but bleed DOT is increased a bit.
