Being a person who qualifies as a judge, but does not have the means to actually take the test. I do not care for duelist network. You have to find people who are not complete idiots. Seeing as nothing is operated, it is relatively easy to cheat. I had someone trying to tell me great shogun shien is a six samurai. ( he isn't for those who don't know, he just supports. That is like saying azure beastmaster is a monster in alteil terms.)
I however have to say if you find people who know what they are doing it is a pretty good site, maybe if you have friends that play.
