@Riot, Creating Mandrake wards doesn't stop the underlying the problem: Perma-stealth is too Strong

Here is the problem, just by the enemy picking up Evelynn, you are forced to spend more gold early getting wards and pinks on this one champion. Even if the Mandrake ward finally does come out, the only people that can effectively use it is Bot lane where the support has the resources to continually buy pinks and wards. The other lanes and jungle can't make much effective use of the wards because there is so many ways to for Evelynn to gank. Also you have to take into the fact that the team that has Evelynn can put out a lot of wards and find where they are pinking and dropping Mandrakes. So players are still wasting gold (especially if they are losing) just to watch out for Evelynn.

You're putting time into something that can be easily solved with just another rework. People would have liked to continue playing as AP assassin Evelynn but it can't be balanced due to the perma-stealth that makes her frustrating to play against. Evelynn had to be changed into a Bruiser because of it where she now has two options: she is able to make (annoying) ganks and gets fed thereby making her super tanky and have strong base damage to kill squishies or she doesn't get good ganks off and is forced to become ONLY a meatshield.

Take the time to put in another rework for Evelynn that has more balanceable stealth on a basic spell ( ) so that you aren't spending more resources on Pinks until teamfights come, not in the first 5minutes of the game. can be avoided with only basic wards and doesn't require full on pinks (or a new type of ward) just to deal with him. If you do the rework then you can end up with a healthy champion that players can like and fill their previous cravings: having an AP Evelynn.
