I feel like I'd be burnt out sooner from riding 15-20hrs a week than a little bit of intensity.
Check your TSS scores. Base rides seem to remain pretty low compared to interval rides. I think its more about giving the body a break while building on ones endurance. For some the constant intensity may work. For me I dont recover real fast, I need the easier time to recover.
