Duplicating a class and with near duplicate roles, is not good.
Say at Tier 5, the Fighter, the Cleric healy, the Blaster Wiz and these two Bards ... everything is about the same = still tier 5 party.
But at Tier 1, the CoDzilla, the Batman Wizard, the built Psi something, and these two Bards are being treated like trainees.
Anyway ... 1 of these would be a decent compliment to Tier 4 or 3 party, depending on the make-up of that party, especially if someone prefers the particular playstyle. But there's really no need for a 2nd one doing almost the same thing.
