Is anyone forgetting the WiFi internet trading? You don't have to force friends to get it. Just connect. I hope you can chat, telling them that it is only temporary.
I dunno, I hate trading with complete strangers. >_< You try having random people walk up to you and ask for a battle because you came in second place at a tournament. It gets nerve-wracking.
Also, goldenquagsire mentioned a "messed-up new attack/spec. attack system". What does he mean?
Attacks like Crunch will become physical (IIRC on Crunch, but I think you get my point), whilst Hyper Beam is special. Basically, if it physically hits the opponent with part of its body, it's physical, if it hits with a beam, ray, etc. , it's special.
But like I said, I'd rather trade with a friend then some untrustworthy stranger over the Internet.
