I like Threnal, its a fun adventure that really delves into the Lore of Eberron.
I don't like how the levels of the Quests work. 8-9-10, 9-10-10, and 9-9-10 or something to that effect. It is so confusing and I never remember what's in the Adventure Compendium, compared to the Quest Doors, compared to the Quest Entry Screens, compared to the Experience Reports. I know they don't all agree with one another and I never remember which one is wrong.
Would it be possible to reconfigure the quests as 8-8-9, 9-9-10, 10-10-11 or 8-8-8, 9-9-9, 10-10-10. or something similar so that it makes more sense running the quests with a Bravery Bonus Streak. I realize the current team of Devs at Turbine Loathe revisiting older content, I think this is one of the exceptions where making the change might attract more players to run the content on a regular basis. I skip the content on a regular basis because it messes with the Bravery Streak, especially when I run a couple early and suddenly have a third of my level 9 quests run before I am level 11.
I would make a similar plea for Tangleroot and Sorrowdusk, however I want to start with the easier one.
