I dont know what you're on about. If anything, there is more "Mountain" today than ever before in mountain biking.
Have you not ever seen a Rampage? Have you never bombed down a world cup downhill course? I dont know what type of expectations you had when you started this "career" of yours but if you're making any money at all for riding your bike you should just pipe down and be thankful.
Jumping isnt for everyone but I dont think anyone can deny just how cool it is to see fat tricks thrown over huge jumps. If they're done in the course of a huge big mountain line, that's just insane.
I, for one, had my mind blown when Brandon Semenuk 360'd his Session off that drop in the most recent Rampage. If that's not the perfect marriage of big mountain and freestyle then I dont know what is.

And with young guns like Semenuk, Bryceland, Fairclough, and others, the sport is looking as strong as it ever has.
