F1 2010 was the 2nd year of the current "technical" car-design rules. The only things that had changed from 2009 was the ban on refuelling and the removal of KERS for the year so that they could revise it due to the many, MANY problems it suffered.
It was Bridgestone's last year in F1 - this was the MAIN change. DRS and KERS were also introduced (and reintroduced) in 2011, adding synthetic passing aides, but it was Pirelli making quick to degrade tyres (tires for the cretins from across the Pond) that changed everything so much.
Bridgestone had created such AMAZING and durable tyres (tires) that it meant 1 stop was the standard. This resulted in car performance, and therefore manufacturer skill, being much more important. Nowadays it's all about tyre management and so any half decent car is now in with a shout of winning.
Upshot is, JayJay - for the purists who want to see the best teams and cars racing flat out to win, since 2011 it's been terrible; but as a spectacle it's (without question) AMAZING!
I see the pros and cons of both. It's still thrilling and intriguing. Plus I think previously "less important" members of teams have become more prominent because of a change in development focus. It's different, sure, but still F1.
