Wizards tower
Someone asked about the proximity of the tower in a different thread (it was a while ago, but I think the verdict was that it hasn’t moved). The Asuran equipment is related to a Peacemaker base there, you visit it during the Asura 20-30 storyline.
Edit: found the thread https://forum-en.gw2archive.eu/forum/game/lore/Wizard-Tower-moving-closer/first#post2831256
A dev posted in that topic saying that the tower had not moved closer. It’s most likely people just viewing with slighting different camera angles.
It’s also worth pointing out that around Halloween last year a new camera depth of field was implemented, so that very well would have affected how far away it appeared to be.
