Ever loot a new item and it looks like it's better, but when you equipped it the stat changes weren't what you expected? Compare Stats will tell you the basic stat differences between an equipped item and one that you are moused over. Besides calculating the differences in the basic stats it will also calculate HP and mana gain/lose, attack power from strength and agility and dps based on attack power and ranged attack power.
Features:
* Calculates the difference between an equiped item's stats and one you moused over.
* Calculates HP and Mana gain or lose when either item has Stamina or Intellect. Also takes into account Tauran racial bonus of 5% to health.
* Calculates attack power gain or lose based on formulas for each class.
* Calculates the added DPS gained or lost from the attack power bonus.
* Shows attack power and DPS changes for all forms if you are a druid.
* Ranged Attack Power and DPS gained or lost.
* Compare to offhand slot by holding down the Alt key. This works with rings and trinkets as well.
