Specifically I've noticed that most kunark zones have terrible zems. I don't know why this is. Someone recommend I go to howling stones to solo, so I got my key, and I only got .7% exp for killing a level 42 mob at level 46... which is pretty bad. In comparison in kaesora I can kill a level 37 mob and get about ..5%. Why is howling stones so bad of exp when it takes a ton of effort to even get in and it's extremely high risk? There's other areas like burning woods that just have terrible exp even compared to outdoor zones and I don't get why.
