Suggestions to remove flash...
Blitz, Thresh and other champions with vital skillshots become god tier.
Ashe, Brand and any champion without innate mobility become trash tier.
Riven, Vayne and any champion with low CD dashes are stronger.
Aggressive plays disappear entirely turning the game into 60-70 minute farm'o'thons for hyper carries.
Frustrating moments that are impossible to countplay increase
ult for example.
Exhaust likely becomes the most common summoner spell. Slowing team fights and skirmishes to a crawl.
Melee's who don't have innate ways of reaching ranged champions become troll picks.
Range champions with no ways of escaping mobile melees become troll picks.
Anybody with large AoE damage or CC becomes pick/ban.
People just complain that whatever next in line best summoner spell is now essential and Riot "forces" us to take it. So nothing is solved.
How exactly is this a better game?
