I might be a little late to the party but I'll give my opinion on the current system vs the proposed QS.
The first and foremost thing you have to ask yourself is do we really need this artificial excitement mentioned previously that gives the weaker drivers a chance to win?
QS might favor the faster drivers, but it is giving the drivers a chance to fight among themselves on as fair as a playing ground it gets.
Taking into consideration that as far as I can tell the drivers, and cars for that matter, are as equal as they've ever been, it might be the perfect time to at least consider it.
While I agree that the current system mixes up the results and keeps it more unpredictable, I don't think we should handicap top drivers just to give the slower ones a chance to catch up.
In rallying often things that are out of the driver's control happen which will give the younger and more inexperienced drivers a chance to raise to the occasion, even without the boost from current system.
