No, it's not what I mean. When I want to play with another player, I don't mind if they are online. It's different than an offline opponent.
"play later" also isn't good enough if I need to skip 20 games.

Here is another idea: Giving our opponents "priority": Normal (default), High, Low, Above Normal, Below Normal.... or something similar. Let me say it advance - it's not like "next game with a friend". Just a way to meet some people more often than others and vice versa.
