New animation for Bards will be the same across all three tiers.
You do an extreme version of the Manderville, everyone feels better, the end.
Though if they changed it, it would be nice if it did more support related things other than just heal/raise everyone.
Perhaps keep tier 1, change tier 2 to a determination up buff, tier 3 can be a haste buff (increased move speed, attack speed, etc). Though to compensate they would need to increase the damage of tier 1-3 LB of melee and possibly magic DPS... otherwise the determination buff would probably be a better choice than a one time chunk of damage :/
Hard to say... Probably why they put so much time and effort into planning things and making sure stuff doesn't full on suck.
