Minor Bard buff.

I think if Bard picks up a Meep, it should lower the cooldown of magical journey, but up the early lvl cooldown of magical journey.

I think it should lower the CD by 1 second, maybe a half a second, but have the CD scale like 21 / 19 / 17 / 15 / 13 instead of 18 / 17 / 16 / 15 / 14.
