I'd like to know how much skillpoints other players invest in each skill.

I prefer it to usually maximize the speed spell and wolfs eye, and I put one point into warcry (more are not worth it)

Archer:

1 or 2 points in repeat shot (more points cost too much mana)
Other points can go to energy flaw, energy shield or even stonewall

Brute:

1 point cleave  (more points just cost too much mana)
Maximize blood strike for high damage against single targets

other points into energy shield and stonewall

Sorcerer:

1 point ice bolt (more points cost too much mana)

1 point lighnig bolt (more points cost too much mana. First I freeze the enemies with ice bolt, then I cast lightning bolt for high damage)
1 point into Lighting strike OR explosion - for instant area damage. Lightning prefrerred because of higher damage

Other points into energy shield or eventually energy flow
