I didnt have the patience to SP Farm at low levels bad move, I know 

 . Now Im at lvl 29 with my full int char. I have my fire mastery at lvl 29 becuase I want my nuke. Will it be worth starting to sp farm now, or should I drop my mastery and wait on the nuke. 
 
My thought was once I reach lvl 30 on my fire mastery to get my nuke then stay there, and SP farm until I reach higher level. The only problem I see is that it takes a lot longer to level, so it will be a while before I reach lvl 39 and get make max SPs.
Any thoughts would be appreciated, especially from someone who has tried.
thanks,
P
