I have been doing dolmens recently because they seem to give really good experience. I noticed that they seem to be toned way down from what they used to be though. I remember when I first started, some of the dolmens seemed to last for like 10 minutes, and have like 5-8 monsters up at a time. Now, only one monster spawns at a time, and it takes like 3 kills (that basically get one-shot) to destroy each pinion.
Have the dolmens been nerfed in recent patches, or is my memory just a bit foggy?
