The time commitment to finish these chains is far greater than intended im sure. unless you get INSANELY lucky on ques, its going to take you 3+ 8 hour days to finish a chain in which PVE raids would take 1-2 hours to complete in its entirety and also they have more chances at the loot they want because of a larger loot table.

Allow all quests to be picked up at once , after completing the chain. or revamp the quest objectives to not be so grief both objective wise and time wise.

Also allow the nightbane quest to be picked up immediately now because if you are mirroring PVE servers, im sure its rare to find a group that does NOT have nightbane urn this far into the release.
