Shows stat gain/loss on item tooltips compared to your currently equipped gear.

There is a main section called "Stat Changes" that shows basic stat gains/losses. Then for each class/spec there is a derived section that make calculations based off your class and spec. That will show how your class/spec might change the base stats and any extra information that "Stat Changes" did not provide to you.

Gems and gem bonuses are automatically accounted for when comparing items.

Commands

/bidzzzmode - will enable a rogue priority stat feature that shows recommended gear for rogues, particularly Bidzzz.

I'm always open to bug fixing. Please let me know if you see anything you would like me to fix or have suggestions of implementing. Thank you very much!

To Do List

look at the 102.4% Cap (Uncrushable): Against level 73 (boss) mobs, the total of your Miss + Dodge + Parry + Block must reach 102.4% to eliminate Crushing Blows. make sure to account for this paladin only.
better account for bis items that are odd out like blinkstrike or idols, librams, and totems. might come down to just hardcoding a list of bis items.
account for all enchants
show same functionality for potions, elixirs, flasks, consumables, and food - show only derived values if possible
want to make a ui for the feature where you could type /bis food, /bis elixir, /bis flask, /bis potion, /bis purple gem and it return what is bis for you except show it as a menu split into character classes/specs to show the bis information. might not want to do it with gems as the code might confuse with the gems already socketed in gear.
let users know when they encounter a quest item that is a bis list item so they know they need it.
fix the slight flicker between ui sizes when mousing over a hover over item. happens to comparison items. probably related to createframe.

Math Is Hard
