User blog comment:Emptylord/Blogs/What if wards were contestable objectives instead of items?/@comment-9245010-20130727205627/@comment-3974211-20130727222733

If these wards were added to the game, it would be with a full overhaul of the map. Brush placement and such would likely be improved, similar to Twisted Treeline's upgrade. There would still be brushes, of course.

The wards would be visible regardless of who owns them, like the Twisted Treeline alters. You would know that the enemy team has sight in that area.

Clairvoyance would become a viable spell once more, with this idea. Items can share the same effect, it's not a problem. Not everyone can take Clairvoyance, after all.

I don't think capping the wards per person would actually solve the issue. It would be an interesting "duct tape" solution, but I don't think it would fix the problem. (I'm not saying my idea does, I'm not justifying my idea by criticizing yours).

And I'm glad it got your brain juices flowing. ^_^
