Love the change, best thing ever.
done lots of them leveling up, its an new word, you get fitting dungeons, no more 3 <20 in IcP, normal dlc is in their right place one tire below vet dungeons.
The change was super nice since I was leveling a healer today. I felt really comfortable going in as a healer knowing that I actually could heal through the mechanics in any dungeon I queued for even though I had plenty of very low level group members.
Changes: certain normal dungeons and all DLC dungeons were changed to not unlock until after level 45. Certain veteran dungeons and all DLC dungeons were changed to not unlock until CP 160. You can still manually enter any dungeon you want.
