So I had a situation in a recent game where we fought an efreeti (Large creature, +16/+11 attack with a falchion, Combat Reflexes among other feats). It won the initiative, so the first thing it did was change size to Huge, afterwards which it just waited. My paladin charged in and, naturally, provoked an AOO -- or rather, our GM ruled that because it had reach 15 ft. and Combat Reflexes, my paladin provoked TWO AOOs during his charge. And the longer I think about it, the less sense it makes.
Essentially, what is being said is that CR allow a Huge creature to make a Full-Round Attack at full attack bonus out of turn in the time it takes the charging (!) character to make a single 5 ft. step. In other words, imagine this 3x3 giant somehow being able to attack a creature rapidly closing in on it, draw its sword (that is larger than said creature) again, and attack it once more with better precision than if it took a full round to do so and the creature was standing right in front of it.
I realize that RAW say that that's how it is, but to me, this particular use of this feat makes absolutely no narrative sense. There should be a rule that a charging character only provokes once from a single enemy, regardless of its reach, or something. :-/
