I've made a few changes and enhancements to item display.
New Feature: Item Comparison
Premium users have access to a new search, which compares a given item to items of the same type/slot based on configurable criteria.
For example, you might want to find all the items better than Smiths Trowsers which your level 21 hunter can get: http://wow.allakhazam.com/db/itemcompare.html?ci=1310&binds=-1&stat1=0&statval1=&stat2=0&statval2=&stat3=0&statval3=&template=&sort1=agility&sortwt1=2&sort2=stamina&sortwt2=1&sort3=0&sortwt3=0&minlevel=&maxlevel=21&dmg_avg=&quality=-1&speed=0&effect=0&showall=0&search=1
I've added some basic class stat templates, however some of them are just guesses based on limited experience with the class. If you have a better suggestion for a starting point, please let me know.
Further to this feature is the addition of drop classifications.
Raid Items are items which are found 90% (or more) of the time in Raid environments. Any item which can only be found in MC, BWL, ZG for example.
Static items are items which can be found on specific creatures. PvP Vendor rewards also fall in this category. This category exists so you can include or exclude items which you might try to get by killing a specific monster over and over.
World items are random drops. Most items are world drops, and can be found on any creature of a given level range, or area. Some might only be found on any Scarlet Crusade mobs in Stratholme, or any level 18 to 20 monster in the world.
Quested and Crafted items should be self explanatory.
Items may have multiple tags, a raid item might also be a world item indicating that it's a random drop off any BWL mob (for example).
The dividing line between world and static is 5 drop sources.
Other features are to exclude all BoP items (for items you might find in the AH), or to limit to statistics of a certain value. ( must have a stamina of 4 to be considered, eg)
All feedback is appreciated!
