I think consistency in everything would be nice.
For example, in the dungeon twilight arbor you can kill laurent and vevina twice in different stories. It would be fine if they were in the same path, but they are both kill able in 2 different paths.
That is very inconsistent. As with everything that doesn’t make much sense. I would suggest maybe just making up a slightly different story with different characters.
It would not be that difficult. Another sylvari decides to try to control the tree instead after killing leurent, and he has different followers. It’s doesn’t seem like a huge difference but anything is better than seeming like there is some alternate dimension.
This would most likely be easy with all inconsistent things. Just think of an easy way to make them consistent.
