i understand your view, but you know that its mainly the intermediate sprints in the mountains stages which are the Sagan strongest card and which make the difference
but yes, well, you know that they changed the rules because Sagan won easily the green two years in arow, so suddenly they made 50-30-20 points system in sprint arrival, just to make the competition harder and as they say more interesting, (which is very unfair, if you finish third you are already 30 points behind, so it´s why there need also the intermediate sprints in the "lumpy" stages to give all kind of racers more or less the same chances.
but sure, I would more like if they returned back to the previous system. but no chance for that, now I´m really wonder what they will invent for the next seasons, maybe 100 points for the flat stages winner and 50 for the second
