Exploit Weakness legendary node and active tooltip both show an increase of x0% damage. I am assuming this is also not being calculated properly in the damage numbers, as the sheet and damage go, my numbers should be significantly higher. But then again, every class except the Spiritborn cant push high tier pits to even get their own glyphs leveled without a carry.
There are other similar bugs with the Rogue paragon board where increase to life show +1.9% instead of +2%
