No, my suggestion is for him to give the group Energized, increased max MP, and mana burst. While I don’t have a problem with your projectile speed suggestion, I feel like just energized would leave bard as a bit of an undesired class and this is a much better way to go about it. Allow me to explain:
Under my Inspire, bard’s increased bow range gives him (her? I don’t know what gender they gave it) about the same range as what the normal robes operate in, making up for the fact that it is a robe and has a generally underwhelming statline (without destroying the game’s balance).
However, you and @Isabell are not giving mana nearly enough credit here. People have already talked about how strong energized alone is in these two threads, so giving a cap and instant restoration is also huge. There are also numerous classes that mana has a ton of value on in comparison to HP, and this argument also does not factor how much you enable classes that do give direct hp. Not only would bard be incredibly powerful for players with weaker pets (this cannot be understated) as well as the strong, but it has a ton of utility for these classes specifically:
Sorcerer - That many more devastations has got to feel good.
Wizard - The above point, but even more so.
Knight - More CC and utility potentials (imagine non scutum perma stuns but with much weaker pet) as well as the increased raw shield damage
Priest - absurdly powerful in conjunction with this class, even more so than it already is
Paladin & Necromancer - Increased heals / more spam as well, albeit less powerful (but you don’t need a ton of heal for a ton of value, and bard + their natural potential is definitely a ton of value
Of course to what degree depends on the final numbers that may come as a result of my suggestion, but to say that it is “not enough” when we can already see the effects of Energized alone seems disingenuous.
