Agreed, and I think that's one positive about Dean Ambrose's title reign too. After last night I have no idea how or where it ends.
The other thing obviously is that he's a face champion that the live crowd actively supports. I don't care much for his matches, but whatever.
To me Dean Ambrose and Sami Zayn are two sides of the same coin. With Zayn, I can't stand his character and presentation but he's a great worker (but not good enough to get me past my indifference to him), while with Ambrose his character is interesting to me but his work bores me to tears. And if I never see that reversal from going backwards through the ropes again, it will be too soon.
Interesting to me though is that now Ambrose can lay claim to having pinned both of the other Shield guys in title matches, which even if he loses the title tonight gives his relatively short title reign some real legitimacy.
