Something I always thought would add a ton of value to the game was movable vehicles. The things they could do with large movable ships, boats, airships, platforms during wvw and group maps etc etc are endless. The only ones in the entire game to my knowledge is the one in Sandswept isle and the airship in dragonstand, both very very very janky, on a set path and hidden/not involved in any events. I have a feeling this is due to a game engine issue. These player driven boats probably wont be anywhere as free or as cool as you would hope. Will probably feel more like a mount and have limited free-movement for other players.
