Warden's Paean is actually situationally useful and can make the difference between someone living and dying in the right hands. It's the only instant cast Esuna-type skill in the entire game, and the only one that outright blocks those types of debuffs ahead of time. It was a big factor in enabling me to successfully tank Mist Dragon without dying last week. I've saved a lot of people in the 24-man raids with it, in situations that a healer would have a very difficult time reproducing with Esuna. I wouldn't trade it for anything.
As for wishlists... I assume the three songs are going to get enhanced in some way. My guesses:
- Mage's Ballad is upgraded to have a 'magic quiver' system, which lets you store up to 3 Bloodletter/Rain of Death charges for the situations where you get procs faster than you can use them, so you end up with less 'wasted' procs.
- Army's Paeon is upgraded to enhance critical hit rate per repertoire stack (up to +8% crit rate, +2% per stack). Most importantly, it is given a 'linger' effect that transfers the song buff to the full duration of the next song activated.
- Wanderer's Minuet is upgraded to store up to 5 repertoire charges, although you can still only expend up to 3 at once with Pitch Perfect.
Other things:
- Have Flaming Arrow come back in some way, maybe as a wind-element damage field since bards are rather wind-themed now.
- Heavy Shot to be upgraded/adjusted so that critical hits have a 50% chance to proc Straighter Shot instead of the base 20% rate. (Or using Barrage force triggers the Straighter Shot buff, but that's less interesting and too easy, as the critical hit suggestion is meant to synergize with Army's Paeon.)
