Yeah, tell that to the Goblins in Dangruf Wadi, or the Ghosts in Fei'yin on the way to the BCNM there who will happily one-shot you if you happen to be on a quest that requires you to go there and your S/I happens to fall off or you need to re-buff and there's no safe spots nearby or what-not.
There are others but these are two examples. How about the True Sight Lv80+ enemies in Promyvion? Someone trying to solo the first few Promathia quests at Lv40-ish might end up getting smeared because he had no idea that there'd be Lv80+ mobs in around Lv30-ish enemies. *SPLAT!* he's dead in one hit (they are True Sight) and Promyvion itself is a maze if you're not familiar with the place.
That, and I have to laugh at some of their enemy choices. Who would XP on Empty? lol. Or ghosts for that matter.
But then the Apex Mobs... anybody who willingly pulls the Matamatas have to be out of their flippin mind because those are so OP compared to anything else there.
