Regarding Lifebloom:
*How the idols work and the effect of +healing on it (people still ask..).
*How much regen is required for a 1/2/3 tank roll (which will help people to understand the mass +22 healing gems depending on raid roles)
*Which clicky trinkets combinations work together, which are the strongest etc.
You might also want to mention about rolling on 4 targets how to survive it when you hit a cascade without loosing all your stacks (just jump one ahead, so 1->3 or 2->4 or 3->1 etc..) because I think most people tend to forget this and try in vain to maintain the order.
You should also include if possible the mechanics and comparisons of Spi and MP5:
info here, to be frank it could use some dumbing down into a more easily understood statement.
Innervate; how much spirit equates into mana exactly from IV (factor kings and/or living spirit, and a scale of 10 is most likely the simplest to use).
How to boost your IV's,
info here, and weapon sets which provide the highest yield of spirit.
ps below, nice call on that macro, hadn't heard about it before and its going to be pretty damned useful
