how did they think edge of night was going to play out??

An offensive item that gives a spell shield upon activation that can last up to 10 seconds.

And you gave it a 30 second cooldown??? So that you only have a 20 second window if played correctly were the enemy can engage you. But you can just play safe for that 20 seconds.

You know what else has a "30 second timer?" Minion waves. So mid game, when a champ picks this up, they can activate it, clear the wave while its active, then back off the wave while its on CD, yet its up by the time the next wave comes. You nerfed CotC for this exact reason. Because it was up EVERY wave, it led to unfair trades unless you had it, and after you proc'd/used it you could back off until the next wave came and it was back up again.

Do you ever take lessons from previous fuck ups? Or do you just ignore them, move on and break the next part of the game? Increase edge of nights active CD to at LEAST 60 seconds, it doesn't need to be up even half of the time it is atm, and the spell shield timer could be reduced as well, so it isnt used solely for pressure.
