Skipping rage skills?

[Namel]

I keep restarting game when I get new ideas so I have never played farther than dwarven lands but I have very few times had situation where wall had been useful and where I had the rage to cast it. I do use stuff like shamans totems, phantom, phoenix or poison spirits armor for purpose of slowing enemy.

Big problem I have had with stonewall is that when I have taken one point of it soon I will be offered choice between more stonewall hp or more stonewall duration which both are essentially useless since unless I really get lot of hp events it wont survive more than one hit anyways.

I am now testing not taking it. I got spirits around level 10 and so far they have offered stonewall twice but both times alternative was good and I picked it. Seems really better way to concentrate on 3 skills making them stronger than 4 bit weaker ones.
