Blizzard has made a point of making a ridiculously high amount of skills & runes, literally making thousands of upon thousands of combinations to use per class. Then why does it feel so confining at level 60 in actually choosing your skillset. The further you get in the game, the less freedom you have to choose skills Simply put, to survive at a reasonable rate in Inferno without being ridiculously over geared you are forced to choose some skills. In our Inferno Wizard guides we discuss a little more of this. While there are occasional deviations from these skills, it is usually from people who have done grinded their way to top tier gear. I would guess in 90% of Act 2 Inferno players you will see these three same active skills.
