As a non-expert, when I get killed 3 or 4 times in a row by the likes of Lynx or Bruv, I move somewhere else. Part of the enjoyment of the game, at least for me, is having a balanced fight. I don't enjoy one-sided victories, AFK kills, or getting totally out-flown consistently. Sure, it makes me want to get better, but a guy can get his headed handed to him just so many times before the fun stops.
I think it's ok where it is...but I wouldn't object to being able to turn it on or off (the post-mortems).
