Ward skins have no use in a variety of modes because wards aren't available, what if...
...in some of those modes, when you die your "ward" drops near or on you. It won't have any health and won't be targetable or grant vision, and will disappear after about 10 seconds.
That might be too often and become annoying, so what if it only drops when you are shut down?
Just trying to think of some way ward skins can have a little use in modes without wards, since they do cost RP. Any other ideas (doesn't have to be related to kills, but it can't take up an item slot)?
