Yes ,you get 2 attribute points per level.
366 seems too low.
Should be something around 700-900.
So maybe the multiplier has to be changed. And there is also the morale state which increased/decreased the damage output aswell.

The resistances didn't change at all. (I believe there were sigils to increase them, but not sure right now)
For the affinity it was 1 attribute point which increased the linked affinity by 0,375. So on level 1 you had 3.75 on all affinities.

Edit: What comes to my mind right now...they changed alot of the skills in later versions, so the values from the beta client data could be alot different from the last update.
