You can have über-steep final climbs without finishing there. The greatness that was the 2010 País Vasco stage into Orio that Purito won (and the tragedy that was Txurruka crashing out from the lead) showed how to do that right. DOUBLE AIA.
País Vasco is absolutely chocked full of possibilities like that, and while there aren't always as many that are as super steep as they are in Euskadi, there is plenty of opportunity to have the same kind of destructively steep final climb without it having to be the finale all over the north of the country. Take this stage from the Vuelta a Asturias:
If you wanted to go all evil "make it harder!!!" on them, you could always replace the climb to Campo Dosango with Cruz de Linares; it would make the run-in to Oviedo longer, but the climb is 7km at 9%. That's more than enough to not need to be an MTF. And in Galicia, the Costiña de Canedo near Ourense is 2km at 13%, absolute Unipublic perfection, but it's only 10km or so to descend back into Ourense, so why not do that? The Vuelta can do it right, sometimes, you know. Try this from 2010:
Hell, they don't even necessarily need to move away from the Murito finishes if they make it so that more than the final 2km count; the Valdepeñas de Jaén stage this year was a step in the right direction in that it did entice a long range dart (though perhaps it would have been more interesting had Kiserlovski been able to stay with EBH and they worked together); take for example this from 2011:
Here you have the uphill finish, but there are lots of hills in the immediate vicinity of it - there are 4 climbs in the last 35km, and practically no flat. That gives the attackers a chance, even if it ultimately ends in the Murito-style bunch kick.
The Vuelta at the moment seems built for youtube cycling; sure you get fireworks for the last 15-20 minutes of the stage, but that's because they're not making it posisble, much of the time, for the fireworks to come at any other time. And the TT is being marginalised. It's like the organisers noticed the smaller gaps coming from mountain stages, and decided to increase the size of gaps by repetition of mountain stages, rather than by making better designed mountain stages, tougher mountain stages or more TT mileage to tempt more long-range attacks.
The scenery is still wonderful, especially the scenes along the coast in Galicia; those short bursts of exciting action in the HTF and MTF stages have been good once they've finally kicked off... I just wish that the riders had had to work a bit more so that they kicked off earlier.
