The problem with a lot of the ideas suggested is that you penalise the top teams for their success. Mercedes has a great engine and even with the rule changes will probably still have the best engine. It depends whether we want a level playing field or not, I personally don't which is why I like F1. There are plenty of other series if you want the teams to be equal. As usual the FIA harps on about cost, whilst actively changing rules that cost a small fortune. I would happily see money pits go like the aero design of the front wing though - what a complete waste of money.
