Will the grove be changed?
It would be a massive story spoiler to all new players. Racial cities are highly unlikely to ever change because of the needed changes to low level zones, personal story, and the flow of the story in general (both spoilers and how it wouldn’t make sense for new players to be going through some other land just to end up with a “and our home [where you never lived, new players] is destroyed” in the plot.
Unlike Lion’s Arch, where only a handful of personal story steps take place and none of which are linked to new players beyond LA instances now featuring a “different” LA, or require moving the player base thus relocating them.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
The Pale Tree’s capable of protecting sylvari in most of Tyria through the Dream. It’s when they get farther from her and closer to Mordremoth that problems arise.
Well imo it should change a little bit for the people who completed HoT story. Maybe not in graphical sense, but NPC talks, especially Pale Tree etc
