Bang on! 2 things I really wish they would listen on. 1: allow messages to your friends/contacts within the game, and 2: Sort out the random friendlies! I've deleted a few contacts over that. It's just not on allowing other players to challenge your team without ample warning or a chance to cancel. It really should be a mutual agreement thing. How did they ever think it was a great idea to allow players to set up a friendly 3 minutes later?!?
I have a couple of contacts who send gifts, and have watched and supported my matches. They're on my level, one in particular was in the first league with me. We've had a few friendlies and have stopped that from both sides now as we've progressed and gotten to know how the game works. I drop in to see how he's doing here and there, and I'm sure he does same. We've avoided being in the same league or cup since. Though only into season 3 for us. I'd like to send him the odd "Good luck" before important matches, or arrange a friendly when both of us are willing, on less hectic days.
Nordeus need some serious talking to. It feels like they set this game up, and are lazy about updating, because God knows enough people complain about certain issues, but instead of fixing those, what did they spend their time doing ... adding in Mourinho teams ... Hmmmm.
