So, I was pretty mad a the new Unity changes, specifically with focus on TSS rather than general elemental buffs and defensive procs.
After redoing my build to rotate around TSS, Elogoth and PRM, I think it is quite good. The DPS is way higher.
HOWEVER…could really use a defensive proc or skill augment on the set rather than some of the minor boosts to TSS on like, ALL of the set pieces. Otherwise you would be locked into very specific class combos (absolute need for a heal on demand). I have a mage hunter, so no issue there, but shaman and other classes with no heal skills get left out in the cold.
That is all.
