Ummm, Bad idea....

Taken directly from here.

In a post on the US World of Warcraft forums, Blizzard poster Tyren accounced Major changes to the possibilities for UI Mods.

Tyren:

"Hi there, this notification is meant to inform you of some significant changes regarding the way we're handling UI addons. Over the last few years, we've seen a number of awesome, gameplay-enhancing UI mods along with a fair number of UI mods that run counter to our philosophies regarding what addons should and shouldn't be able to do.

Essentially, we don't want UI mods to make combat-sensitive decisions for players and as such, we've made some changes that block functionality that we feel is counter to the spirit of these philosophies. As such, AddOns and macros can't make decisions on who to target or what spells to cast.

That being said, our programmers have implemented a host of new functionality in order to allow many popular and benign UI mods to continue to function (once those mods are updated to take advantage of the new functionality), and will be providing some follow-up information on these forums as to how to take advantage of the new functionality."

This essentially means Addons like Decursive, Detox or any Autobuff Addons which intelligently pick targets and cast spells will no longer be functional.

Ummmm.... I can see where not being able to use auto/smart buff won't be THAT detrimental since you have the group version buffs, but not being able to use Decursive? Unless they create some sorta group decursing spell for each class, this change is going to make lives of paladins/druids/mages/priests a LOT harder than it is now. Since most of the endgame fights have bosses repeatedly using the same debuffs on some fast timer, this basically means that the classes that can decurse will all develop Carpal Tunnels. It's okay, it's not like I need to be able to use my fingers/hands/arms anyways.
