Yeah, that spec would work just as well. Only problem I found is, when you piss off a lot of mobs while running around with out the pet to take some of the damage from SL, you can die pretty quick. My lock has only 8K HP and 10K MP, she is not all that powerful, but I can run through all SM pretty darn quick, both the higher levels of SM are 12mins under. Thats with a little bit of breathing room.
