Hey I was wondering if anyone could inform me on downranking, and how to utilize it as a paladin.  From what I've read so far you dont need to downrank your Flash of Light since it's already super efficient.

Though I've heard my big heal (the name escapes me right now) can be downranked.  Though when I downrank to the point where it's still ahead of my flash of light, I'm still using alot more mana.  

I was wondering if I just need to rotate using Holy Light at a super low rank, just to keep the buff that makes it cast quicker for when I need to throw the big boy.  

Any would be nice :)   I'll bug you guys instead of researching it myself :)
