Bard End-game using Iron Jaws to re-apply the DoTs, why not combine Caustic Bite and Stormbite together as 1 ability that apply 2 dots then we can remove Iron Jaws and saved 2 ability slots.
like from lv6-lv29 just Venomous Bite
then at lv30-lv63 add Wind Bite to Venomous Bite and lv64+ is Caustic Bite + Stormbite
I dunno how much this gonna effect the DPS because both abilities have potency on cast then DoT potency after change we gonna lose 1 potency on cast but we get to DoTs the targets faster, this part I'm gonna leave to devs.:p I'm sure its gonna make Bard feel smoother to play. In the end it just my opinion, Thank you!:)
