"exact" min mp formula probably wont be determined until we get in for a bit in GMS. As far as hp/mp gain per level its slightly less hp then warrior, slightly more mp then warrior.
looking at the "Aran Flaunting Thread", the first 2 pics seem like same medal/same armor, 3 levels apart (though might be wrong) so doing math from the assumption there isnt random hp/mp gear that one has over the other (believe their medals add both, but since same medal irrelevant) it looks like 47 hp/level and 7-8mp/level. But like i said, one of them might have extra like 20hp from an item idk about.
edit: bored so going through that thread more looking for more people with similar/identical medals and calculating hp/mp per level lol. Though this is more likely to be skewed due to differing hp/mp gear on random armors.
LadyReflexx level 31 and StatutoryApe level 50: Hp = 46.5789/level Mp = 6/level
StatutoryApe lvl 50 and himself at 53 : HP = 45.333/level , MP = 5.6666/level
LadyReflexx and Hazzy's Aran(sorry me no read korean), HP = 46.875/level, MP = 5.563/level
StatutoryApe lvl 53(no need to do him twice) and Hazzy: HP = 45.167/level, MP = 7/level
and other then the level 20 who could throw off whole average due to job advance gain, the verdict seems to be over the 4 avg mp gain warriors get, but under 8 mp. And hp seems like under 50 over 45. So there you have very close to a dam good estimate on washability.
