Only battle litany is a raid offensive cd but he is pretty much right, dragoon has a lot of buttons and oGCDs, now put aoe abilities in the mix and we are easily at 20 buttons just for rotational use you have to bind.
I think with role commands im pretty much at 31~ bindings on my hotbar for dragoon.
I don't see why that's a negative or a problem though, FF14 is differently paced to WoW so the flowing rotations are part of the fun.
