1.2.0 Freezing Pulse/Power Charge/Crit need help

Hello,

i tried creating a freezing pulse witch build and i need some Feedback.(Softcore)

Some Questions:
1.) i suppose it is to much offensive orientated?
2.) 135% mana reg and some mana reg from gear should be enough for AA? (98% increased max mana / +252 to maximum Mana)
3.) is only 18% increased castspeed enough?
4.) Ghost Reaver is nearby so if i get a Shav(unlikely) could i switch to ES and maybe use Pain Attunement
5.) maybe EB + MOM Armor?
6.) Build Worthless? xD

all in all there are so many possbilities, i dont know what i should focus on.
