Technical details on spell downranking

[Tsunami]

I think the impact of these changes is hard to guess because of all the other things that get changed. If it weren't for the larger health pools, I'd say that I will STILL use more lower ranked healing spells than anything else. But if the squishies have like 7k health, a Heal for 1.5k isn't what it used to be.

Maybe I can conserve some bar space now that my setup of Renew 7/10, Heal 2/4, GHeal 2/5, Fheal 7/9 seems to be obsolete.:)
