In the past two days I have seen no fewer than 10 ragequits. It's not exlusive to NA players either; I've seen roughly the same number of D/Cs from every place on Earth so far. Bad sportsmanship doesn't discriminate.I have been using my RNG'ed 4th gen Pokemon in the Random Singles so far since I haven't bothered to breed/raise any new 5th gens yet, but its frustrating since everytime I am about to win a battle my opponent quits on me. I have 0 wins on my trainer card because of this, I have yet to have someone take their loss like a man.
I can kind of understand how someone would D/C to not give their opponent a win if that opponent would have won by ridiculous crithax in combination with a terrible, unworthy team. But when your opponent beat you with an obviously more capable team? I don't quit when some 200+ win JP player steamrolls me, what do you gain over your opponent by quitting except spite?
I ragequit one time, to a player with QC Salamence that kept activating, in tandem with a Double Teamer who had Guillotine. In spite of still feeling that he didn't deserve to win, it is a nasty, shameful feeling to quit and deprive someone of a win, and I regret it wholeheartedly. The person deprived of his win will forget that I did that, but I'll probably never forget that I ragequit.
I'd like people to know that D/Cing on purpose is petty and self-destructive, but I doubt most of them read Smogon anyhow.
EDIT: I'd also like (or have liked) Nintendo to implement a couple things: D/Cs count as forfeits (Even if this meant getting a loss from an accidental D/C, most people I think would still agree to it) and, as an incentive to stay on, what PBR had: Exchange trainer cards, and by getting a lot of cards from other people, one would get a reward. This would keep people staying until the end, I think.
