1.3 EK AA RF?

Hey guys i just wonder if there is some way to play RF,AA,EK due to the new skilltree i feel like its rly easy to pick up 8% + regen. Ill prob req phoenix but im not pretty good at planning threes so far :) also im still not sure about which class (witch sion or even templar) but i feel like sion is best due to the fact i can skip the line between the left and right side of the skilltree. So just leave me some feedback or even help me to improve the three.
Id be thankfull :)

EK is better off without RF, usually (whether Crit or not). But if you insist, it's generally doable as you say.
