Have this poll across all LoL boards and you'll see universally that people want to be able to zoom out more. The handicap of having to play unlocked all the time from the purple side is just too much, just constantly managing the screen is so annoying that it sucks the fun right out of the game. So what that it can be done, it's completely anti-fun, it defeats the reason why I play this game, FUN.
Giving people a narrow "paranoid" view is a weak excuse considering how much of a handicap it causes one side. The total winrate for blue has always been higher despite the matchmaking supposedly putting the more skilled side on purple, that's not a coincidence. Also, I call BS on that supposed balanced matchmaking, I'm on purple 90% of the time, I'm not that skilled.
