Pink Wards Are Bad
I think the complete removal of pink wards is a big mistake. Players now have absolutely no way to see evelyn, shaco, rengar, etc coming until they are right on top of you. And if you do use a pink ward, then the enemy team can instantly destroy it. I think there needs to be a ward that gives vision of such stealthed champions even if it does not give vision of enemy wards. It is really hard to deal with certain champions, such as the ones I listed, and keep them from snowballing without them.
