I found this question interesting, as I used to be in the same boat.Why is it that I've had my team battle-ready for about three days, but I haven't yet asked in the Wi-Fi subforum for a battle? I feel unconfident in my ability to battle with 6v6 Standard teams, although I know that I can predict well, etc.. maybe it's because I'm still unsure of who would disconnect when I would be winning? I don't really have a way to prove if someone disconnects, I could only hope that EE and Eep take my word for it.
tl;dr: I want to test my team but I can't ask in the thread full of potential disconnectors (obviously except for Faladran), and I don't want to individually ask random trustable people because it'd seem awkward to just randomly request a battle
The way most people do battles is with PO or shoddy, but if you want wifi-matches, dont feel awkward about asking people on the wifi-forum. Feel free to post something like "I want a battle" on the battle requests forum, like most people do. Smogonites are much nicer than people from serebii, or any other forums.
If its the awkward thing you are worried about, think about it this way. most of the people here want to have battles anyway, and if you were requested a battle, it feels like a compliment. It certainly does so to me.
If its the D/Cing, I'm afraid I cant help you with that. But if you recognize the person that you are battling, you can always have a rematch and replay all the moves if you remember correctly.
TL;DR, there should be a battles subforum under wifi and a battle requests thread. There are many people aching for battles there.
