yeah. theres nothing we can do about it.
the game should be played with an "open-world" mode, so that u can go anywhere, but Haseo decided to make it area by area, so u are stuck in henesys until u can enter the next area. I think Henesys is the worse area in that aspect, more area that open up better it get. sheep are terrifying until they are not. so its all about your character level and power.
but if u avoid those area and levelup from area u can own, eventually u can enter those area and kill everything. the same is the golem area and boss area. u are supposed to be level50+
so, do side-quests (u have that guy in henesys that gives u missions to do) he will help u levelup.
but, another thing is that in Henesys u learn (that hard way) that the player is not invincible, he can die and easy. it will give the player the feeling, damn, theres tough monsters and its scary. even if frustrating its also challenging. the problem is if we added "quests" that u need to do and require u to enter those areas. but at least u have the potion so u can do them and leave.
