Out of sight, hopefully. Yes, it is very different and something else entirely, you shouldn't be trying to
understand it because as it stands
it's not canon.
This is what happens when you come up with vastly alternate takes on different map. Some people are just confused and looking at things in disbelief, even after reading the "reimagined" word, because it's just that unprecedented. If I didn't know that from this forum and haven't seen Scenario's confirmation/explanation and first time experienced in game... I would probably stare at the screen trying to figure out what's up, not to mention the confusion of Dol Guldur towers in it. Can't remember anything like it from any game/sequal I played. Well, maybe between version 1.0 and 3.0 of a complex mod a change like that would be noticeable
But yeah, not good if LOTRO devs turn into outright modders in their approach to the game, it is its own different thing where the rules are : can change entirely any time or modder may just abandon it, not that you pay for it anyway
PS: Not that it's going to happen but... I would gladly launch it into the skies, gave it a cool point over so it's not overly Angmar and fix some of the tower situation, and then dropped somewhere in Nurn for later use
Or for Angmar Besieged map and the tale of the Witch King's defeat, though some narrow mountain passes would still need to be added to reflect OG terrain. But if that's pristine version and shares some of the layout, then I could see how some of these city district collapsed/were destroyed by water leakage after whatever destruction the good guys brought to it which would result in a more watery legacy version.
