In which case that season was pretty much balanced out in terms of car issues, at 3-3, whereas this season seems to be falling more to Hamilton having things break, this kind of thing is probably best filed under 'shit happens', although for some reason it just feels like Rosberg will be a more fortunate* champion, if he wins it.
*not undeserving, every champion deserves it. Just fortunate, and they all are, to a greater or lesser extent, just look at Hamiltons first WDC...
