Review my build: Self-cast Ice Spear for 1.2

For the new leagues I'm thinking of running Ice Spear,Lmp, Faster casting/spell echo, Pcoc, and ele prolif. Might change Pcoc with crit multi. Might mess around with using added lightning and chain. I am running EB. Dont know what uniques I might run. Will be running AA, clarity, and some purity aura (havent decided yet:P). Will use flame surge for single target.

This is my first build and is in no means done or even fully planned. I have most of the groundwork done, but would like to hear what everyone else thinks. Thanks for checking my build (er theory crafting) out! :D
