Why I have no interest in Coils more specifically, T9.

Yea but it is kinda a way to "prepare" you for harder divebombs. I mean look at the opening video. Bahamut divebombed over eorzea. But what you didn't see was the megaflare dives he did DURING that. But yea, you can't really cricitize certain things that are changed since its a way of preparing you for the next version of it. t5 divebombs you move when the mark appears. T9 you move then it Disappears. Same thing, different flavor.

Also, one could very well consider that the 'signature move' of the Dreadwyrm's closest minions, one that even he himself uses. That's a case of careful theming.
