Depending on the party composition and mp I change Grasp of the Dead to BBVD (Boogie Man) or Soul Harvest (Vengeful Spirit). But the above build is soloing.
Works best with pickup radius in your gear, 20 feet preferably.
A few people have asked me to produce a video demonstrating this build and I will gladly do so soon as I 1) buy a mic and 2) get 6 more yards in my gear. It will be mp10 solo, but kindly take note you do NOT have to be mp10 geared to use this build - lower the mp accordingly and enjoy!
^ for farming the challenging mps solo (9 and 10 for me)
^ for farming with a party not including a CM wiz in challenging mps
^ for farming with a party including a CM wiz in challenging mps
^ for farming non challenging mps where dps barrels everything and you get a subsequent AR increase as a result of the increased int (added protection because who isn't careless in lower mps?)

solo mp10 elite kills and build tutorial.
With bears I can kill reg mobs with ease on mp10 hence popping zombie dogs which I sacrifice to gain full mana back. At best I can spam bears for nearly 30 secs or longer given that mobs within my PuY range are also dying because I sac my dogs The passives GI and CoL take advantage of this.
At worst I come across an elite that is tough and all by himself with no other mobs around him and I have to wait on the CD of dogs to come around and just use spiders with mana return rune to get mana back to spam bears for a few secs and back to spiders again.
EDIT: 4/4/13 Trying this build with a zombie dog reduction SoJ makes it work sooooooo well and I've seen dramatic improvements on tackling elites, though clearly I am sacrificing EHP it is well worth the trade off.
This spec works best (along with high dps and survivability gear), in a group setting where things are dying within my PuY (pick up yards) keeping dogs sac'd and globes are dropping where the passive GF returns mana (and gives me a dps buff). Also boogie man rune in BBVD is quite nice to keep the dogs sac'd and the mana unending. EDIT: Also because things are dying fast by using the passive GI all my cooldowns get reduced by a sec with each bad guy I kill within my PuY. That means Zombie dogs don't take 45 secs. More like 20 secs or so at best, and BBVD does not take 90 secs, nor does Mass Confusion take a 60 sec cd. Often times that time is cut in half. Which is why I keep 14 yards PuY minimum (though I'd rather have 20 but that would sacrifice too much dps and or ehp).
When solo I have to take off BBVD for mass confusion/devolution rune for the obvious defense concentration in mp9+.
