Unless you descend back down to Pinos Genil and go up Hazallanas again, Monachil is pretty much part of the same climb if you're going to Pradollano from there though, even more so than Télégraphe + Galibier. Attacking on Monachil on that stage is kind of attacking early on the final climb in my book.Contador attacked with Bardet and MAL on Monachil IIRC, which is harder than the first 5km of Velefique, and of them only MAL survived against the onslaught of the Sky train.
There's no defensive Sky train this year, which is the only advantage todays stage has.
I would also say taking GC from Culoz instead of Anglefort didn't help, but I wouldn't have been surprised if it would still be a Pog vs Rog uphill sprint
