This concept could have been great if given the attention it deserved, but it never got that.
Flawed with bugs, bots, and unpunished trolls, Riot did little to try and fix this game-mode and now they're just abandoning it.
I loved this game-mode greatly. It was different, it had the renowned 'hide and seek' mini-game.
But now it's being removed simply because Riot couldn't be bothered to look at it.
