So I've just finished boosting 4 alts to level 40 in SFK and SM. I'm leveling up two priests and two warlocks to join my 70 warlock.

I used my Warlock for the boost, mostly SM Cathedral, using the talents and technique here:

Was very tedious casting dots on everyone, but I couldn't seem to get the SoC technique to work reliably. The leveling time was also a little slower than I hoped, about 30-50 minutes per level, taking about 15 min to clear cathedral each time. Not sure if it can be done any faster without a prot pally though.

So I understand the next step is ZF, but I can't find much info online about the pulls and the best way to do it. Any tips on best specs and ways to do the pulls?
