Anthony,
550 yards is not exactly short unless the tee shot is downhill, the hole predominately plays down wind and the conditioning of the course continues to be firm.
A well placed tee shot leaves typically puts players in that 200-230 yard area. I have about 7-8 rounds on the course with varying hole locations. If the pin is on the front of #10, that's a massive backboard to hit into. Fan it out a little right and the ball is in the gully. Bail left and you're left with a heck of a tough pitch shot. Play it short and you still have that massive backboard. If the pin is up top, I've found it easier to play well left of the green. The fairway extends quite far left of the green to allow players to reach the same plateau the pin is on. There are many options to explore on this hole which I find quite fun. To me, the hole has two separate greens (although Jack proved a putt can be made from the bottom to the top tier).
Quite frankly, this green, while extreme, is more playable than hole #15 at Crooked Stick. The boomerang green on #15 just doesn't work. The contouring won't allow putting like the 7th at Crystal Downs can.
I understand your dislike for the green, but stating that #10 at Harbor Shores is the worst modern green ever designed is more than a little stretch.
