@Riot: Can this be done?

Is it yet possible to create permanant paths on the map, such as having shyvanna's dragon burnout scorch the ground, or xerath's w leave the ground with a static-looking zone?

Possible implementation-have alternate meshes of the rift which are linked to champions abilities of the champs which are in the game, can be walked upon, if these abilities affect these zones, replace the mesh of the area with the corresponding x-y coordinates of these other rifts

(im trying to look smart about the suggestion, though it's propably not the ideal way to do it, it would work, right?)
