The worst two balls on the table are the 15 and 13.
When I determine patterns. I don't look at what should happen if I everything goes right. I place more weight on what can happen if things go wrong.
The most position critical ball on the table is the 15. It has one pocket, blocks another ball, and the transition from it to the 11 makes or breaks the pattern. Keeping all that in mind. Why on earth the correct play would be to pot the 13 first with the goal to play shape on the 15 is beyond me. The 13 gets me out of the corner relative to the 11 with ease. I want that 13 after the 11. If I under hit the 13 first, or even get a kick, I could be left very thin on the 15 if not possibly snookered. The 15 is frozen to the rail so any angle your generating off the 13 now requires you to slow roll the 15 to insure a decent shot on the 11. You don't want to spin down the bottom rail as it's way too easy to get flat on the 11 and get into position wherein you need to work the CB out of there.
Although it's easy enough to use the 10 last, it does allow for some cueing errors to bite you in the ass. It gets worse when you're now attempting to play shape to the 13 from the 10. The transition from 10 to 13 boils down to how close you get to the 10 after the 14 and the cut angle you're left with. So how good are you at moving the CB with accuracy over the distance of 9-10ft and 1-2 rails..? It would be incredibly easy to under hit the 10 and end up blocked by the 3. It's just as easy to over compensate for the potential under hit and leave yourself a cut angle on the 13 that now is going to run you down table further than you would like for the 8. That may go as bad as being forced to play 3 rails to get back to above the 8.
None of the pitfalls are all that terrible, (other than the snooker) and a decent player could work themselves out of any of them. However why even take the risk...? Why play a pattern that relies on shot making ability and better than avg CB control. When you could literally just roll the CB around and get out without any risk of snookers.
