I
decided to play with maximizing opportunity attacks, figuring that a
fighter with Combat Superiority and a really good OA might be useful in
certain situations...
This is all about maximizing to-hit chance (and, secondly, damage) on an opportunity attack. And quite frankly it's overkill on to-hit. It's Twin Striking on OAs and will score a double hit on a pair of 2's against enemies well above level. With a +4 attack bonus if its previous swing against the same enemy missed.
The OA damage is less impressive, averaging 27.71 at same level. That's 6 OAs to kill. (Fortunately, you'll rarely need to kill a non-minion with just OAs.)
But... Combat Superiority. The enemy might as well try to run through the wall.
