About Mandrake Wards...

A little time ago I discussed about how stealth was problematic and there was no point in gutting stealth champions until they got stealth right. http://boards.na.leagueoflegends.com/en/c/fancreations/21Hkkk7N-sentry-ward-item-suggestion

"Place an invisible unit on a point of the map with 3 health and a 5 minute duration, which doesn't provide sight of the area but is able to reveal units. When a unit, regardless of stealth, moves into the ward range, it will trigger an alarm for the duration enemy unit stays in the area and a color icon upon the ward based on the distance from the ward."

Told ya , Riot. Told ya.
