Not matchmaking with other players

Anyone else failing to find or get people to join games ine the last couple of days? Is this a matchmaking issue or mass exodus of players?

As soon as my Characters reach level 30 (having 3 now) the matchmaking seams to often only match with other 30s , and i often have games with less people or even no one dependant on the time.
As long as i am under 30 it seams no problem to find people. Maybe you mean that
