Where are the Axe skills?

I would just be patient and wait till they give us much more skills than we got now.
I think GGG is trying to make "skill types" for now, like traps, cruses and then they will expand each group type with more skills.

The thing that bother me most is that axe dont have unique skill for just that weapon. I guess it will be added in future, the game needs much much much much much much more skills and the whole skill system should be somewhat upgraded since for now its plain boring and redudant, favorizing only small % of total skills.
