There are very interesting simulations for d3planner. DMO wizard can do INSANE dps. Sure most simulations are done with Paragon 2000, 90 gems and all ancient gear with 450+ stats, but that can be easily changed. I never used that feature from d3planner but seems very useful. Makes it a lot easier to decide what's best for the party.
