Loving how some of the skills have been rendered utterly useless 
Ignore Pain, caps damage reflected at max hp? So you can reflect a wopping ~40k maximum? Man those enemies with 300k+, elites with 1-3mil+ and basically anything in coop must be quaking in there boots...
Caltrops now only stacks up to 10 times? Short of people using Caltrops, Prep, Caltrops, a technique which does not work in Inferno, how the hell will you get it on a single target 10 times?
Replace Nether Tenctacles with Ball Lightning again. It normally hits twice anyway, even if it is for less damage. The life steal effect is worthless to the point that Blizzard may as well not have bothered.
Diamond Skin - Mirror Skin, it now caps at 11k damage. Wow, what little worth the rune may have had is now gone.
