One thing i think would be pretty cool is it there were items around the world that different races can interact with to give them buffs.
Sylvari= Plant statue that when touched makes the statue come alive and fight with you.
Asura= Pile of metal scraps that creates a golem to fight with you or creates a suit of armor that grants buffs
Norn= Animal statue that releases a spirit that give the player a buff depending on what animal it is.
Charr= Box that has various weapons depending on type of box.
Human= A god statue that grants a buff depending on which god is on the statue.
Each item will scale up depending on the level of the area. The items can only be activated one at a time so a player can’t go around activating a bunc of them to stack effects. Each item has a duration and a cooldown.
