The closer someone is to an enemy champion, the less dissatisfied they are when they die to that champion. People hate, absolutely hate, dying to Karthus who is on the other side of the map, or Lux who lasers from a screen away. People are less frustrated when they die to a close range attack, like Cho'Gath's Feast or Shaco's ganks.
I think this is because people feel that distance should equal safety. In most circumstances, safety is correlated with distance very heavily, but there are other factors at work. Most people don't understand positional details beyond distance and line of sight. Even that takes a while! It takes newbies quite a while to understand bushes and how to deal with them. Distance is the simplest positional mechanic. It's the one everyone thinks they understand. They think "Distance = Safety".
And when it does not work the way people think it should, they get frustrated. There is always excitement about getting the kill with Lux's laser at long range, or Pantheon getting a beautiful man drop on an enemy team. I think the positives out-weigh the negatives, especially since better players overcome this poor intuition, just like new players overcome the urge to face check bushes.
Question: Will you be coming out with more champions that violate "Distance = Safety"?
