I honestly understand the overall idea, but having a specific distance for the damage could really cause a huge problem just like mentioned above ^.

Anyhow, hope there will be found a proper solution for this that will be acceptable and fair enough for both bad and good players (and we all know it's not easy at all). The current situation in-game is just frustrating and I do agree with what you feel.
