WoW Solution sought for Heroic Strike/Maul

In the context of a follow-up to the Warrior Q&A, Ghostcrawler mentioned something that he's touched on a few time before: Heroic Strike is a problem. I know what you're thinking: Eliah, you don't have a level 80 warrior! What would you know? Well, that's true, but I do have a Druid tank, and Maul is essentially the same as HS. So I know your pain.

For those who don't, the problem with HS/Maul is basically that it's obnoxious to use in a raid situation. You tend to have roughly infinite rage, so you want to use the ability as often as possible, which contributes to the fact that your main tank sounds like a woodpecker is attacking his keyboard (or mouse) when he pushes his Vent talk button. It's monotonous, but you have to do it to maximize your threat.


Recognizing a problem doesn't mean they have a solution yet, though. One idea GC had is to make it consume more rage the more you have (like Execute). Personally, I might like it if it just automatically activated above half rage (or so). Others have suggested that the key act as a toggle, which continues casting HS as often as possible until you toggle it off. What's your preferred solution?
