that being said, HeRO being a 5/5/3 which often goes to 7/7/3 means that the grind is also so much shorter compared to regular RO and is pretty decent in terms of drudgery vs reward (anything over 20x exp rates are just not rewarding imho)
all the custom quests and events also help on this, so i think the grind in HeRO is quite enjoyable
