I would say my build is a combination of thorns / tank-proctor. It has worked great especially for a casual budget player like myself! I've probably spent +2mill TOTAL on my current set of gear in the AH, with a few lucky drops. I beat Diablo solo with this build and can farm A3 with ease.
10% CC (Immobolize, Stun, Freeze, Slow)
I experimented with Gruesome Feast over Zombie Handler, but my pets seemed to die noticeably quicker (Guess the 20% HP is a lot) plus I think the thorns dmg by the 4th dog does more than the 10% Int Stacks dmg of Gruesome Feast. Maybe I am wrong, but it just felt like I was clearing mobs faster with Zombie Handler.
Playstyle is pretty easy. Sit back and spam RoT, AR every few seconds, horrify as needed, and run around and pickup health globes. Proc's go off VERY often, especially with Acid Cloud!
Aiming to upgrade my LoH to about 800, DPS closer to 30k, and pushing thorns as high as possible!
