WowAce

From the EBB main page:

Due to changes Blizzard made with WoW 4.x it's no longer possible to cancel buffs without the use of secure frames. Currently EBB limits canceling of buffs to out-of-fight since using SecureAuraHeader would have required a major code restructuring. This will be coming in a later version.

1. This is annoying. Someone in my raid group cast a costume on me that also pacified me. I didn't realize this until we pulled, and I could not cast any spells. I just told to healers to ignore me then stood in a corner until I died. Also, I cannot remove my Ice Block and have to stand there for the full 10 seconds of the effect, even if I only needed it for one second.

2. According to your home page, Blizzard broke things in WoW 4.x. We are now using WoW 8.x. Do you still intend to make this change?

3. A workaround is to enable the Blizzard buff bar, which I've just done. But the entire purpose of this addon is to replace the Blizzard stuff with something far superior.

4. As much as I like Elkano's BuffBars, the inability to cancel buffs during combat is a deal breaker. After tonight's fiasco, I'm going to try and find a different addon to manage my buffs.
