Challenges are way too easy

Make challenges that involve doing specific flips, grabs & grinds. Include specific flip trick to grind/manual sequences like hardflip to crooked on the rail, or laser flip to manual to inward heelflip, stuff like that.

I also hate how when I complete all the daily challenges in only a few hours, I have to wait till tomorrow for the challenges to rotate so I can continue progression. The game really slows down when you complete the main missions, especially when the side challenges don't give me enough rep points. It's now taking forever to level up because of this.
