All you folks talking about rage quitters, I kind of have that situation, not because I'm rage quitting, but because my wifi can't handle a single battle. o_o I don't care as much when I'm losing, but there have been some battles I'm about *this* close to winning, and then I see my little signal thing go red and then... UGHH. It kills me that I have this team I've worked so hard on and I can't even win one battle because of my stupid wifi!
Also, like everyone else has said, the GTS. My wifi can stay on long enough for me to use that one. I tried just meeting people's trade requests, but that doesn't seem to work because of all the impossible requests, so I just bred an army of Spiritomb and ask for whatever I need. One thing that really bothers me about GTS though, you can only trade for a pokemon if you've seen it. That really doesn't help! At all!
