What could be changed is the quality system of this year.. I really didn't understand anything from the player quality thingy.. Somehow I managed to stay up that list but don't ask me how =P I don't exactly remember how that was last year but I do know that it was easier to figure out. I just won a lot of 2vs2's and my quality kept rising up, I guess it was about how many games I won (or something).
Further hmm.. I don't really agree with Superjazz there. Like Enigma said, it might be better for you personally, but some people are studying and/or working full time in other seasons, so after a day of hard work and working for like 8 (or more) hours, I don't really feel like to duel to "get my round score". About that vacation thingy, I was just lucky I didn't had to go on vacation this year and last year so I could participate every round. Next year I WILL be going on a vacation though (dunno how long) so feel free to take my place on that throne .
I did had fun this season, but I figured out the way of working of JDC.. and it was no big deal to get high round score points. Just duel somebody with a high place in the player quality to get high opponent quality, when that´s done, play a lot of 2vs2's to improve your roast:fall and your pts per duel and you can win every round if u want to. I don't know anything to change that.. but maybe somebody else could think of something to change that way of scoring, coz it simply just was too easy :P.
