I really see no need for another communication channel, i.e. Discord; that's what the forum is/was for, and by creating a new communication channel it just takes away the support from the forum... and puts the problem somewhere else.
I don't use Discord much (except to talk to one or two friends occasionally), but I was invited to join one of the WGT groups in order to find games. And what a mess it was - I left the group after just a few days! My point here is that if everyone stopped using these forums and went onto Discord, it will be no better (and very possibly a lot worse because it's real-time chat) because everyone will just move ALL of what is currently in the forum to Discord. And imagine 100 people complaining about 100 different things all at the same time - I certainly wouldn't want to be a mod for that, nor would I want to be one of the 90+ people who aren't replied to. At least with a forum the mods can take their time to go through the threads and reply where necessary in a more relaxed manner and timescale.
To reply back to the OP, having seen live streams in action where the game representatives explain a roadmap of upcoming changes, and then a free-for-all discussion session... the last part just doesn't go down very well at all, for similar reasons as I outlined above for Discord - too many people asking too many questions and only a very small handful getting answered, and often not to anyone's satisfaction.
My advice is, keep discussions and suggestions in the forum. And now that Icon has gone and has been replaced by someone who seems to care about the membership rather than just himself and his small circle of friends, I think things will be looking up in the future. And Nico's passion to help and interact with the members seems to now be rubbing off on Champion too, meaning we might now have double the support we had before.
