Guild Wars 2

There are a lot of things to break, smash, destroy in this game but most of them are related to events or heart quests. Of course you can “interact” and destroy them even after the event is over but it not giving an incentive to do so.

I remember we had around Christmas a dungeon Toypocalipse where we could actually destroy and smash almost everything not only if we wanted to, but involuntarely just putting a fire spell or a sword swing.

My suggestion is to create all over the world smash-able, destroy-able environment other then those needed for events, that would react to the spells or hits taken from random use of skills
I think this would really make the world more real.
The timer these environment items will spawn back will be around 20-40 min so it will seem "more"permanent destruction.

There is a place in Planes of Asford where if you fight some ghosts near some ruins (there is Vista point too) the skills break involuntarily the walls and the walls collapse .
