BB Comprehensive Guide or Q&A?

So, dumb question, but do some of our base HP stats get increased after the big bang?

I saw something fiel posted about the formula for applying Ap into HP got upgraded for some jobs, but what about those of us who already put 30 ~ 50ap's into hp before hand?

A lot of classes got skills that increase HP by 20% or something post-BB. And HP doesn't matter as much (check me on this one) since you can't hit mobs at a decent rate until they don't one hit you, anyways.
