This is a valid concern. On the other hand, the state of map control through wards in its current state is not, in itself, entirely healthy, as in the latter stages of the game you can lose the match by getting caught through a ward, without knowing what you did wrong (besides not warding). Conversely, giving each ward the health of a Vision Ward would force your opponent to delay their movement and spend a significant amount of time stuck in the same area as they try to get rid of the ward you placed, allowing you and your team to collapse on them. Proper ward placement, i.e. placing your wards in the bush, would make it so that you'd have to be within the same bush to notice the ward anyway. Effectively, wards themselves should be mini-objectives, which players should be able to create and contest. That's one of the reasons I want Sightstone to be generally available, too: past the laning phase, everyone should be trying to ward as actively as possible in addition to completing objectives and hunting down the enemy team, and so the loss of wards in the enemy jungle through their visibility would be counterbalanced by the costlessness and ease of access to wards.
