Last expansion when it opened messed up our experience rates to a lot slower than live and with the open wing of seeds of destruction I feel like the same thing has happened
I have also noticed this and power leveled in SoF in the same zones as i am currently in SoD and my chars are getting half the amount of levels they were in SoF so something is definitely wrong with the current xp rate on coirnav
Nothing wrong with the XP on Coirnav It's widely known that the XP in most of SoD's zones was just completely & utterly crap, Korascian Warrens, Kaesora was Okay & so was Old Bloodfields but certainly the earlier zones your XP for levels is mostly from tasks, kill xp from mobs was really just bad. Most of Phinny probably levelled to 85 in MG.
im talking all level all zones not just new zones i power level toons all the time and the experience is most certainly different from last expansion to this one
