Looking for a build that can do all map mods

Best build I've found that's capable of doing most mods without a problem is Righteous Fire Blade Vortex.

Usually I'd say Summoner but, let's face it, when the entirety of your gameplay is based on minions with the AI of a shoe, you're fucked in a lot of scenarios. RF/BV handled nearly everything except No Regen maps. Combined with Cybil's Paw, reflect isn't a problem. Your sustain is through the roof and with max block, you're capable of tanking a lot of damage.

Like I said, no regen would be the obvious problem. Don't think flask spamming would help there.
