The 146 crews may well head out the door, but it won't be a new situation! Having lost 1/3 of the flight deck crew they've managed to get lots of low-hour guys/gals to hop into the company, parting with cash up-front.
For the routes that it does, it is a good aircraft. I'm not entirely sure why you have to slate it so much when you don't even fly the thing. It's kept the company going - you should be grateful for that otherwise you wouldn't have a job!
