It doesn't even sound like we disagree much then, to me the smoothness of EW GNB feels "fine" but I don't have much ShB GNB experience to compare it to. GNB's lack of a simple loop is almost certainly because of the increase to the ammo gauge, the bloodfest change, the 2 cost on DD, and the way the recasts on all-of-the-above interact. This means the hole that DD fills in each of its recasts "looks" slightly different than, say, the state of a PLD each time they cast Confiteor. This is the sense that I mean it's more "flexible", because its forced to fit a wider range of states than, say, Confiteor. This is half of what makes GNB feel compelling to play at the level of execution of rotation, but I'm also happy to concede that the very same mechanics that give GNB that flavor cause the problems you mention in your earlier post.
I can't say if this is an oversight by the devs, but the way the numbers look and the execution feels, my impression is that this is an intentional feature of EW GNB. I do enjoy it, but if they do end up changing it and I enjoy the result more I will, without any sarcasm at all, come back here and say you were right.
