Its not that bad, they just need to add armor to mojo`s to give us that extra bit of survivability. Mojo`s are useless right now. Might aswell go for 2h that has more stats and dps if you go for glasscannon.
I`d also like to see extra scaling to the armor/def of zombie dogs. They become useless after act2 normal. Even with an absurd +vita stack build. If they are not meant to tank why use them? Sacrifice makes them just a glorified nuke with a 60 sec cooldown.
Vision quest is kinda out of proportion to be honest because its almost mandatory. I suggest making mana regenerate 150% better passively and give vision quest a 150% increase. This leaves room for more builds without VQ that still have some sort of mana regeneration.
Locust swarm requires you almost to be in melee range to even hit enemies, which is fairly dangerous on hell. It would be great if the range got extended as far haunt goes. Results in better synergy. Oh... and put some sort of a timer on mob health bars or anything that shows how long the dots still go for! I cant really see if enemy`s are sometimes affected by my dots at all.
