I wouldn't exactly say RBR 'dominated' last season. Should they have dominated? Sure. But they dropped the ball and nearly lost the WDC to Ferrari. They barely squeaked through at the end with a bit of luck and some very mature driving from Vettel.
Here's to hoping that Ferrari and Red Bull are a bit closer matched on pace than last season. Looking forward to the discussions to come!
Predictions: RBR will the fastest, but will still suffer from reliability issues. FA will show more of his characteristic consistency than last season and make it another close championship. Mercedes and Renault will mix it up from time to time, and Mclaren will be struggling to get on the podium.
