This quest originally had a max level of 7 and was raised to max level of 10 only as a grace period for the end of the chapter. This quest should return to the level range it was originally intended with a max level of 7.
Maybe when there is more level 8 content readily available..
But please not now.
Also not in favor of this one. Seam quests are pleasant content in which characters of all levels can partake in together. Just the same, it's one of the few pieces of content higher level characters can partake in. The difficulty is adequate for the reward it provides, without specifics, so as to not suggest the difficulty (or possible lack thereof), as well as any perils that are essential and part of the quest.
