Why are you so happy to make all the new shiny champs have very little risk but huge reward?
Zed? Made a bad trade, let me just teleport back away. Talon? Jumped badly? Let me just ult and jump a wall. Eve? Let me just iframe teleport out and heal it all back and if you chase, does damage while running. Infinite summoner spell Zoe speaks for herself.
Meanwhile you look at people who didn't get the Meddler Treatment
Rengar, jumps in? Oh look, you're stuck there now. Tough luck kid, you don't generate enough Shekels for papa Riot. Shaco jumps in? Yep, stuck there until you die.
Quit this burst hyper mobility design trap. It might make your LCS moneyfest a bit more exciting, but it makes the game itself boring as fuck.
