HP washing questions for all classes

Hmmm would it be impossible to get that hp without doing that method? What if i just wore int gears and washed like normal? Also if possible how much int do i need to wear? Remember i'm aiming for 8k around the 17x area not level 87 :/ That method would take far too much nx and time >_>

int 140,wash 204 times
to level 179,hp 8034
int 160,wash 215 times totally
to level 170,hp 8034

It shows that you need 140~160 int with gears to reach the goal.

It is unbelievable to do hp washing without mp wash in CMS,because we have 25% more level-up-EXP than other servers.
so it's really hard to train a lv.150+ chara...
