I dont think that logging out is fair at all. Losing 50 points at 1000 is the equivalent to a person at 100 losing 5. Dying and losing said points is part of the game, how many of the people that do this deserve those ranks when every time they are about to be killed they have logged out? They have taken points from countless others to get as high as they are, but as soon as someone lower than them manages to kill them, god forbid that person should be given points like they would have been! It is NOT fair on those who have lower scores, who scrape to get any points because those higher either dominate and win, or log out when faced with death.
There should definitely be something in place so that people who log out while a tribute you should drop your items and lose the amount of points you would have by getting killed.
Obviously im not saying that every person with a high score practices this, but a good number of them do, including donators who can log out without fear of not being able to get back on.
tl;dr Deal with it, cry more etc.
