Improved Tracking's requirement of constantly swapping tracking types annoyed the ever-loving crap out of me, so I did what any good Engineer would do and fixed it. I sat down last night and created the TrackThat! addon, downloadable now from wowui.worldofwar.net.
Here's the description I put up on the site:
TrackThat! was designed in response to the Improved Tracking talent, introduced in the WoW 3 patch. The increase of 5% damage to targets being tracked is nice, but the mechanic of switching tracking types in-game isn't nice at all, just annoying!
This addon simplifies life by changing your tracking type to match the type of mob you have targeted, if you're capable of tracking it. Just add either of these slash commands to the top of your main attack macro:
Yes, this works in combat! No, it won't kill you by continually tripping the global cooldown! It's simple, it's functional, it might even be international.
Good luck out there, fellow survival hunters. Let me know what you think!
