To my experience,the only players who are concerned about points are those who know they can make it to the top 25 ( and perhaps top 10) if they work hard enough at it. Those who do not have the skills to achieve the top 25 don't care - nobody will see them anyway on duel ladder. Those who can make it easily don't care so much, because it isn't so much of a challenge.
Personally I have quite a natural e-peen like most people. I love to show all players that I am one of the top 25 duelist on EU. However, I prefer the fun of duelling to this 'pride', so I force myself to give out all my points to some random guy when I start to feel the need to stop duelling to not lose points. It feels good afterwards. I can duel for fun again and stop raging when I lose lots of points for a few fuck-ups.
Of course, this is my method, but many players will want to keep their points and climb to the top. It's natural. That doesn't change the fact that yes, indeed Panos, this kills the fun of duel server, and that something should be done about it.
However, since our 6th of january ''present'' ( makes me laugh how we all expected to recieve something that day and we ended up giving away 40 000 euros haha) it is unlikely that 'devs' will spend their precious time on the old limping c-rpg to improve it.
