Unpopular opinion-bringing back green wards is not a good idea
This might sound crazy but i have some reasoning behind it. LCS is very important to riot, there is no denying this, and green wards are inherently not good for LCS. If we had the green wards, then LCS would turn into an incredibly passive game. The whole map would be lit up, ganks would be useless, and the position of enemies would always be known. In a meta like season 6 where damage is high, snowaballing is insane, and just a few kills can win a game, playing safe is necessary. If green wards were still in the shop, the whole map would be lit up 24/7 in LCS and high elo. It's just not good for the game to let everyone have a ton of access to vision, it encourages playing safe too much and the meta would turn into a safe lane game. Is it sad that you have to deal with a darker than usual map? Yes, but compared to games where the map is almost completely lit up and ganks are almost worthless? nah.
