I agree that Ranger could pretty easily be implemented as an alternate job option of Archer, adding some slightly higher potency abilities (nothing crazy, mind you, but maybe something with a 200 potency attack that chains off something else, such as Heavy Shot -> Sidewinder). Could even throw in a positional attack (i.e. Sidewinder = higher potency from target's flank).

It'd shape Ranger into a more single-target oriented ranged dps as opposed to Bard's AoE + songs setup, which would provide enough of a change to make it feel unique.

Whether or not Yoshi will ever do another 1-class into 2-jobs setup is another question entirely, given how SMN and SCH had such issues.
