I wouldn't like Qualifying to be scrapped. I find quali laps very good to watch, a different kind of spectacle from the race. However, I would like that some changes be made in order to avoid impeding and slip-stream tricks... ahem... clever strategies.
Maybe, make the cars leave the pit-lane at a regular time interval from each other. As the exit order may favour some drivers over others, let the drivers choose their respective slots in reverse WDC order. Depending on weather or other factors, it may be more advantageous to start the lap early, or late, or in whatever middle slot. The WDC leader will have to make do with the only slot that remains at the end. Ideally all drivers should have the possibility to get at least 3 hot laps, maybe with Q made of 3 sessions. If this would make Q a little longer, then be it, more fun (and more ads/rights money). This procedure may result in mixing things up a little bit without resorting to some more unpalatable randomness to "spice up" the race, though it wouldn't be the revolution some seem to want.
With the great difficulty in overtaking due to cars and tracks, the propensity of some drivers to shove others off, the likelihood of some drivers to crash out and take somebody else with them, combined with the fastest cars being in the back and the likely "agreements" between A, B and C teams, I'm not keen on the introduction of a sprint race on Saturday even if the usual Q is not removed.
