I made myself some excel tables, they show you how many points to spent on the main attribute and dexterity & cunning. It's just putting your base damage, actual crit chance and actual crit damage in the first row. It works for Rogues, Warriors and Mages (put R,W and M under class). It also works for spells and talents, when the Spell multiplier is 1 it calculates for auto attacks. If you don't have Devious Harm (Rogue only) put 0 under it. The Attributes Spent are there for you to know how many points to spent into the attributes (pretty obvious) and for the 100 cap, they have no impact over the damage.

These fields you can and should change, let alone the rest if you don't now what youre doing.
I hope this helps someone.
