It's not fair that 98% of the riders have not a chance to win anything. Next year move the race to Nepal and go for Mount Everest. Then only 0.1 % can win. This is not a fair competition and not exiting for any wievers. Suggest 50% mountains and 50% no mountains. This is more fair for all the riders and will be much more exiting for us to see.
50% mountains? That's actually something that not even Angelo Zomegnan in his golden era has dreamed of.
Generally speaking, I don't really see why GTs should favor classics guys. They already have the classics. Pure climbers don't really get to win a lot outside of GTs.
I'm also not sold on the idea that having plenty of classics-style stages would really give more exciting racing. Riders would still identify a few decisive stages and soft-pedal the others. In most cases, they would also soft-pedal the decisive stages because of the following decisive stages. Finally, they would soft-pedal the final decisive stage because it's too late and you can't afford to lose your GC placement with an attack from far out.
I also believe every race has its own dna. Saying that - for example - the Giro should have an edition with little to no mountains, so that guys who can't climb can win it, is like suggesting that Paris-Roubaix should skip the cobbles every now and then, so that guys who can't ride on cobbles can win it.
