On my hero I just broke 15k HP @ lvl 132, Its more of a blood build at this point, but I plan to reset whenever there's a sale. But washing for warrior classes imo is well worth it. I'm not sure about aran's hp gain per point as you don't have improving hp gain. If its anything close to other warrior classes you should do it if you plan to play your character past 120.
Pros:
Increases Survivability - I haven't really purchased a safety charm in a while. I can enter oblivion maps without worrying about getting 2hko. I can also walk around crimsonwood forest without being instakilled by bigfoot.
Pot Reduction - If using percent based pots your can go well below 1hp/1meso ratio. I'm using ginger ales which heal ~11000hp/3700meso. This is ignoring the mp gain which is a nice bonus.
Bossing - You can do some bosses earlier (Latanica/HT comes to mind) Some bosses for certain classes require washing PB. (Not sure about arans, but archers for sure.)
Cons:
Lower MP - Dojo was an issue at times.
$$$$ - Its very expensive. As a class that gains the most hp using this method I gain an additional 250hp per level washing 5 times. Other classes only get a fraction of this. Without a sale thats $15.50/250hp. You also don't feel it unless you do it in large amounts.
Regardless of whether you do it or not now, you should wear INT equips,
Even 40 int is a bonus 4mp which equates to 1 more wash if you decide to in the future. If you can somehow get to the magical 190 INT, you can wash every level.
