What solution are you expecting? Group matchmaking is still dependent on the right number of tanks/healers/DPS being queued in the system. SE isn't going to force players to choose tank or healer as their role just so you can get a faster queue.
I would imagine most of us who tank and/or heal did what you're doing - leveled our tanks and healers first so now we're trying to level our DPS.
At least once you get to 71, you can switch to using Trust to bypass the wait.
