With the free respec weekend coming, I am considering trying out a max critical chance % build. For a sorc, that will probably mean I spec into Fire, Light, Gale and Ice, all of which have "increased damage on a critical." And using pets like Ribbit, Aspen, Horton and McCraw.

I could not find any posts saying just how much dmg normal criticals add (some suggested maybe 25 or 50%), nor could I find any posts saying how much damage "increased damage on a critical" adds Consider also that some of the best +critical chance % eq sacrifices a little bit of damage. Case in point, the Archon Ring of Force, which adds a whopping 6.38% critical chance, but lowers my damage score by 7.0 when I am wearing a a purple Ruby Band of Brutality (36):

What is the general consensus, is maxing critical chance % worth it?
