I played Diamond up until just after the champion elite four thing, and stopped... but I'll probably get this and get more into it cause I'm a fag.
Alot of shit didn't do that, like PBR 6v6, unless you wanted gay 50 cap. And I think you could only do 50 cap for 3v3 also. I forget. Anyway it's also used for boasting. In all my other games I had a team of 100s because thats just how it is when you vs in RL too. Dont really level cap there.
