the idea was to try making the fights less tedious mostly raid bosses by tweaking the stats not all stats are lower some got raised and certain skills and stuff got nerfed/buffed
personally i haven't even reached level 50 and i did the dungeons just fine i have like 120 hours on my save. also i seen a couple people complaining on the forums about how tedious the raids could be. who knows maybe thats now why he did it im just somebody putting my view of why i think ryen did it.
