I got around to UP my HP a little, got my res a notch higher and sacrificed some armor rating.
I am contemplating to discarding armor and switching out freighting aspect for something else. Problem is is I can't still figure out to keep phasebeasts away from my tail. Even with 700 res and fierce loyalty fetishes or the gargantuan die.
I'd imagine it would be possible to tank them out with some ridiculous amount of life on hit but I can't afford that.
If u could post some screenshots of your gear, I could probably give u some better feedback on where u could improve. I've completed Inferno with my WD, who is now currently benched because I don't find it very fun to play. If u want to go for a proper tank doctor build, u will need some LoH and probably more hp and resists. If u r happy to just do a standard ranged build then all u really need to do is up your DPS a bit. So I guess it sort of depends on whether u want to just solo it, or keep tanking for your group.
If u have problems with phasebeasts, try using mass confusion and/or hex fetish.
This is a legitimate tank build if you have enough LoH. You can even drop VQ for Bad Medicine if you get 50+ mana regen and have a slower weapon I think. Or you can switch to Firebomb and get PtV, but that's really worse imo. You can also get Hedge Magic but you really don't want many short cooldowns with this build I don't think. So you'd swap it out for Soul Harvest, which doesn't seem worth it at all. You can get Paranoia too, could be better.
