Zenga covered it but to reinforce it ... you mana issues go away if you put judgement into the spam macro on the same target your minions are on to avoid threat issues. If you judge every CD you will not go out of mana. Alnd use might for the regen as well and alot of +int +spirit gems initially. There are some great JC trinkets out there to help you out as well if you can get them and are a JC.
