The current qualifying rules resulted in less cars on track, especially Q3 which was traditionally the most exciting with 8-10 cars circulating trying to set the fastest time right down to the final seconds. We had no cars on track for the last 2 minutes of Q3.
I don't think the old rules were boring at all. Quali has traditionally been pretty exciting IMO.
It merely changed when cars were going around.
Usually there was a 5 minute period of nothing happening in Q3, because everyone was waiting for the final 3 minutes to go out.
In Q1 and Q2 it also was barely any different, unless conditions were wet/changing.
Nobody on the grid has tires to burn on unnecessary runs.
Now, if you gave them one extra set of tires, and made it 5 ten minute sessions with 2 minutes breaks in between and drop the slowest 3 after the first 4 sessions, there's more action, less room for mistakes, and more opportunity to gamble. Give every team that doesn't reach Q5 an extra set of the softest tire for the next race, to mix up the grid occasionally. Top 10 have to start on the the tire they used during their fastest run.
And yeah, Kimi's engine fire really gutted me, put a lot of (fantasy-)money on him getting a good result...
