Larian DS1:
Action Points are very strong

Larian official talk DS2:
Action Points a very strong so you have only 4 to 6 maximum per Round.

Laian: "pse come here"
Player: "What is it"?
Larian: " When you combine Invisibility (enemys make nothing) with this Starter Rogue talent you can have play like having 2 times 6 Acion Points and exploit the fuck out of it"
