Okay I must be the Cedar Point genius here let's get all straightened out. Top Thrill Dragters is the tallest and fastest coaster in the entire universe at 420 feet and a 120 MPH launch in less then 4 seconds and the hill is 90 degrees. Millennium Force was not the second tallest and fastest a few years ago but the tallest and fastest at 310 feet and 93 MPH, it is also the best ( in almost every poll including golden ticket) roller coaster in the world, and currently the 3rd tellest and 4th fastest (not including Superman at SFMM). Cedar Point does have the most coasters at 16, but also has 53 other rides, with not one but two kids sections, one of which being very new and modern. A park does not get the award for best amusement park for 5 years in a row for just coasters ladies and gentlemen, Cedar Point is your average park on steriods. Every thing there is bigger, better, faster, more thrilling, and more diverse, while still having great mild roller coasters, rides, and family attractions. So any more questions on the Point?
Now Back on topic, I would take out Face/Off and replace it with a full B&M inverted coaster elsewhere in the park. After riding Alpengeist, Raptor, and Batman, the coaster does nothing for me, and the capacity is horrendous.
Edit: Millennium Force would not fit where Top Gun is, It is only 805 feet shorter then The Beast, with just as big of a footprint.
