So, Big Bang and hp washing/mp gain?

Sorry if what I'm asking has been partially covered elsewhere, but I'd like to get some straight answers if they're available yet about the big bang and what we know as hp washing.

1: So apparently they're giving normal characters an increased hp levelup bonus. This is also given to current characters - is it also given to hp washers? Is there any sort of hp penalty for washing done?

2: Have the mp/hp pool been separated making it impossible to hp wash or has it become disabled by some other mechanism? Do you still gain extra mp from leveling up with int gear/extra int?

If you can answer any of those with some certainty, I'd appreciate it.

My studies around the forums have yielded the following answers:
No penalty for hp washing, hp before & after kms patch was the same (someone on Sleepy had an SS).
You can still wash if you want to (no change to the pool) and I assume no change to the int gear - but the conversation I saw was regarding the possibility with the hp/mp pool.
The only hp changes I've heard about for sure are regarding warriors.
