True Blade
Wind
+100% agro
+100AC(increases with mod)
Add weapon proc: Deflux
Allows bards to be offtanks (obviously they shouldnt compare to a real tank), but often x content needs 3 tanks and we have two online. Usually a monk/ranger can do the job, but making bards a bit more viable in such a role could be a nice utility.
Expose Mind
Flute
300mana/tic
Reduce all resists by 50
Target takes an extra 10% damage from all critical spells
Mana cost makes it situational, but would be nice for burn phases, stacked with caster curse.
Insidious Weakness
Percussion
Reduce AC by 100
Reduce all resists by 50 + 3/tic
Target takes an extra 2% damage from dots
I mostly see this one being used vs mobs with crazy high resists, eventually it allows casters to be a lot more effective. The AC is just to give a little something to meeles and dot damage because percussion = dots.
Lcea's Lament
maybe let the hp regen mod up to 100-300 a tic, and a couple extra overcap FT for super ultra healing intensive fights where you might want this and mots over fiery or anything else?
Motivation Drain
String
Reduce meele damage of target by 3% + .1%/tic
Generally not worth the lost weapon/song, but for those ultra rape meele bosses like corefire, this is your song.
Some of the numbers I used probably need tweaking, but those are some ideas.
