What does this mean going forward?
In general, the system is highly expandable, which opens the doors for our team to create and implement a lot of things that were previously impossible. Something the community has requested for a long time are interactable Stronghold decorations. Imagine your whole Guild meeting up and leaning across the bar, sharing drinks after the latest successful run. While this idea is not a guarantee, it should help paint the picture for things that we can do that never used to be possible!
Suffice to say that the developers are aware this is something a lot of players are after. My fingers are crossed for 6.0 on this, or at least some time soon after.
