For the fastest solo climb using easy mode (max of 2 mobs) what abilities do you think are the best? Below is what I think would work for the classes I've played, but im still pretty new so im open to suggestions.
Barb, Fighter, Rogue: Power strike & Retribution
Samurai: Power Strike & Multihit
Mage: Powercast & Doublecast (maybe pillar/pierce?)
Some of these aren't 'blue' skill for their class, but I would think the abilities that target a certain row or column are less efficient because only 2 mobs are spawning and often at odd placements to each other.
