I was wondering if
A) there is an addon or
B) someone could make an addon
that is similar to tank points, but works for different classes. This is insipired by a post I have seen on a different forum which gives a relative value of 0-1 for each stat for warlocks, and can be used to compare items.
Just think it would be an awesome addon and would be very interested to see it made, being as I don't think it would be massively difficult (although i can't do it myself, have no addon building experience)
