Attack of Opportunity timing is confusing

[Colette Brunel]

The fighter's Attack of Opportunity needs better wording for its timing. As it stands, it is currently unclear on when the attack takes place; it could very well occur after a ranged attack, or after a creature has moved, thus making the attack invalid in the first place.

Disrupting on page 297 would suggest AoO occurs immediately after the trigger, but immediately before the effects of the trigger occur, so as to disrupt potential spellcasting and the like.
