Noob needs advice with a basic cyclone build

Im still mostly a noob when it comes to making efficient builds, i have played one archer build to lvl 60 but thats about it. Im now trying my hand at a cyclone build, starting with duelist, ascending to slayer. I was wondering if Vaal Pact is necessary for cyclone builds? heres my skill tree as of now:

As you can see im still in a very early stage in the game but im not sure if i should focus on the axe nodes on the left (im currently wielding a woodsplitter and plan to stick to two-handed axes) or if i should go for vaal pact and life. The reason im not so excited about vaal pact is ive gotten lots of nice items that have good health regen like a unique coral amulet and the vaal pact basically makes these obsolete. I really have no idea what i should invest my levels in after these, so can someone point me to the direction i should head next? Also are two-handed weapons better for cyclone and how important is attack speed for this build?
