PoE Raise Zombie, gandalfintraining builds

This is my backup plan for league start next league, if nothing new/buffed piques my interest, and if armour and evasion both somehow avoid the nerf hammer again. Zombies seem to have a very low representation on the SSFHC ladders, but it's pretty easy to get 1M+ damage on them with a ton of budget left over for tankiness. 1.2M DPS with the Determination/Grace/Defiance Banner trinity, 100% spell suppression, and 62/37 block. Any suggestions for improvements would be welcome!
