Rengol maps are pretty annoying on rogue. I enjoy running my mage there for this reason. Less time stunned, a whole lot less annoying. However I still run it faster on my rogue even though I spend more time stunned.

For elites a 2 nekro party will be a must. It is going to make pugs impossible and players will not be open to running with just anyone. It takes away some of the joy when you can only get in a party when you have the best and most expensive pet in the game.
