stat addon

[yami]

hi

im always hearing different things on whats best for dps, my main is now an enhance shami, and at first i heard she needs x amount of hit, and ap, then its expertice and haste, even though i originally heard that haste is bad for an enhance shami..@_@

so im wondering if there's an addon that will scan your toon and say ok, this is what you need for the best dps/etc.

hit cap, expertise, ap, haste, crit, armor pen

same thing for casters
int, spirit, spell power, crit, haste, hit

numbers are always changing n im tired of going crazy trying to remember whats what...like for example, how much hit does a dw enhance shami really need @_@ i've heard anywhere behween 12-16%...

so thank you for the possible help/addons as always it's greatly appreciated
