Ranged DPS, choose a weakness that would justify a buff

[Lastelli]

looking at an all fights metric (just to smooth out outliers) bard is about 5% below mch on all percentile levels, dnc right now seems to be even weaker

This should make you realize that fflogs data is not all that matters. If DNC is weaker, why is it the preferred choice for speedrunners even now? Of course, it means that despite fflogs showing DNC as weaker than MCH and BRD, that's actually not the case, as fflogs is stil not perfect at estimating the effect of party buffs, especially in highly synergistic compositions.
Anyway, I'm not against a minor buff to BRD single target dps. However, if that were to happen, stormbite, caustic bite and iron jaws should receive the gnashing fang treatment and become a 30 seconds cd (20-25 seconds for iron jaws) linked to the gcd to mitigate multidotting abuse.
