I guess you have Discord. But it would be nicer if already implemented into the game client itself. (Just like a deck tracker for that matter.)
Yeah, it might not be worth it. But maybe they will make eventually something like this:
And for that it would be very good if we had something like a lobby for such custom game modes.
But until then I agree. It’s probably not worth it. (And that sucks.)
Why is this always such a big concern? You shouldn’t force it upon people and make everything optional. Even now if you accept a friend request you can get “abused” (but you really shouldn’t be offended at such things anyways). But just in case and of course if the other is too annoying with spamming whatever you can just either not accept the friend request in the first place or de-friend them. And the same should apply to such “guilds” (or however one might call it). If really necessary they could even put a warning up.
