Ken's complete Shaman macro set - feedback welcome

[Ken]

Ken, why don't you want the brain to have focus on themselves?

So it can identify itself as being the brain. This way, macro's like the 'follow focus' don't complain about not having a focus target. This could also be used for casting(or not casting) certain spells.
There's no "am I the brain?" or "is he the brain?" check possible in WoW, so this is my workaround for it.

Also: Characters that don't have a focus set will behave (with my macro's) like a normal character. So macro-functionality buttons will become normal use buttons and - for example - cast spells normally. In most cases this worked already, but it would complain about the "/assist focus" because there is no focus set.
