Funnily enough, they actually got it paved in 2012, just to never use Reiterjoch again!Yeah, I understend where you're coming from on longer climbs, we need variation. A MTF on Bondone for example would be really cool.
About really steep climbs, it depends. If they are only really steep near the top and used as a MTF I agree. But steep near the top and a downhill finish or and easier climb afterwards is different. It's also different if the really steep part comes right at the start.
And yes, Pampeago is part of the Dolomites and you can do great stuff with it, if you don't just use in as a MTF.
