No, I don't imagine it would be that big of a deal, but I enjoy being the best I can be, and that generally means understanding everything. If I can get 2-5 more DPS, why wouldn't I? If an item is better, there's no reason I shouldn't use it, right?
This is a fair point, but that's why I asked if the ratios looked accurate in general. Obviously it's all going to change depending on the fight, your current gear, your group, etc. Stamina isn't very important on fights where you're not taking damage, but I don't really want to know the exact ratios for every fight or anything. I mostly wanted this for leveling purposes, anyway.
There's enough people out there that can calculate what the 'best' item is at level 60, but very little (or zero) information exists about what is good before then.
