I think you have to go back to 2004 as the last time there was a developing system with a good upper-level environment that went through the Hebert box, approaching from the ESE.
Ever since then, we have seen system after system get taken down by the strong shear around the Leewards. This year, the synoptics did open up the possibilities of systems getting far to the west. But it seems that when this happens, the shear does the job to kill the system. On the other hand, when synoptics were present that would recurve systems E of 65W or so, the upper-level environment seemed better, but it didn't matter since the system was recurving anyway.
There is something about that area around the NE Leewards (or just east of the Leewards) that keeps killing systems.
