Double HP washing is screwed over?

I just tried out 5 AP worth since AP resets are so cheap. The only problem was... my HP gain from double resetting blew chunks.

This was when I decided to add into HP after taking out from MP:

HP: +18
MP: -16

Sadly adding into HP didn't care if I had the Brawler HP skill for +20 HP per AP.

And due to a grave miscalculation, I borked up badly how much INT I wore before I tried double washing 5 AP. I ended up losing 25 MP, and only gained 80 HP. Looks like no double HP washing for me pirate.

Moral of the day? Double HP washing can only work for warriors, since they only need at the least 40-50 INT to double wash without losing MP in return. Archers and thieves need 120 INT, and pirates need 160 INT.

Double washing only works for Thieves, Bowmen, and Slingers. Since with Brawlers and Warriors the extra HP we get from our skill doesn't work.

While Warriors have less MP taken out there is still the problem of it costing a lot and not really being worth it unless you're really high level and haven't HP washed at all.

Double washing is better off just going normal washes two ways for anyone with HP increase.

1) AP into MP, reset MP into stats. (gain minimum MP + int/10, lose maximum MP = int/10-2 gain - for 160 int, you gain 14 mp, etc.)
2) AP into HP, reset MP into stats. (lose normal MP)

If you have enough +int, these pairs don't lose you any MP since you just reset the MP you just added, so you can still do it after you wash all your normal level-up MP out.

It just takes 2x as many levelups as the double washing that bowmen/thieves can do.

My pirate is leveling with +171 INT from gear, is it possible for me to double wash 5 times per level consistant? Doesn't it mean I gain 15-17 MP per AP I spend into MP?
