people who have high lvl aran

The thing is, not everyone can afford HP washing. A basic level 150 of each with equal stats equips, the Aran would be better in multi-target training and probably lower, more unimportant bosses like Papulatus, where as Heroes would be better with single target DPS and would have a much easier time at Zakum, Horntail, Pink Bean, and the like.

... see maybe im just surrounded by well funded people, but i can't imagine someone at level 150 not being able to get their hands on some nx. Heck, my plan for Aran is when i hit 128-131 just grinding at obliv and selling the PoTs, then using MTS for conversion. And HP aside, I believe Aran's would be better in HT and the like, due to better buff from SE.
