It's truly hard to believe that 2012 was already almost a decade ago.
I agree - I think that had we had a good handle that the complex would maintain intensity as it approached, we could have qualified for a high. The sheer number of reports backs that up. If there was the equivalent of "post season analysis" like they do for hurricanes, that could have been a high risk day IMO.
I doubt we ever see a TOR based high risk in this area. Although...isn't it more about the number of reports than the intensity of individual events? Say we had a vigorous system (perhaps tropical in nature or hybrid) and it was clear that while there wouldn't be EF-5 stuff...we'd get a large amount of EF-0 to EF-2 and it was high confidence - would that be enough to trigger a high hypothetically? I doubt SPC would ever do that for a tropical system, though.
