The few times I did go online when I had better WiFi, that was so annoying. It's like they're afraid to admit that they're not the very best there ever was.
Not over WiFi or Pokemon Online. A reliable WiFi connection is an issue for me (finding one of the right security level is a pain), and building a team on Pokemon Online doesn't keep my interest as long as other things I like to spend my time doing happen to. I will battle people on online forms of the TCG if I have the time, though.
