Bard and Machinist isn't a SMN or a BLM, we don't have the same power output or play style to either of those jobs even right now so that's incomparable, Bards/Machinist have abilities that are still instant too. The difference between SMN/BLM and BRD/MCH is that we can swap play style at will given the situation and BLM/SMN of course does more DPS.
I for one like Iron Jaws how it is right now though, it's a sweet ability and it's with a cast time like a song would be regardless. The animation doesn't matter much as the effect of it is clear but I do love the animation of it and sidewinder as well.
