I just had an idea for a new addon, and since i have no idea how to make it i thought id come here =)

Well, you know how you can shift click on gear and see how it looks on you? Well, what if when you did that you could see how it would affect your stats (ie what you new hp would be at with new gloves) also, after all this was done if you could add enchants and different gems to see how it would affect it aswell.

=) just a thought. Man id even pay for that addon.

erm... you have something similiar, displays on Tooltips the comparisons, even on the 2 ring case, displays comparisons for both :)

BTW for this to work, it's not needed to preview, just mouse-over the item in question.

FYI default for WoW equiptment comparison is press Shift+hover over item.
