What fiction would that be that allows all 30 orcs to go first(they won initiative and there is no surprise) and all move up to 60 feet and/or attack before the fighter can move a muscle, yet still make sense?
Except that it doesn't. Waffles come from mechanical effects such as the confusion spell. Stumbles happen because of the trip and other mechanics. Freezes from from hold person and other such effects.
And as I pointed out in a prior post, those narrative delays result in ridiculousness if you have multiple PCs that lost initiative. The fighter stumbles. The wizard who goes after the fighter now has to have an even greater narrative delay than 30 orcs moving AND a fighter who stumbled to explain why he goes after the fighter. Now the rogue who rolled badly on initiative goes after the fighter and needs a narrative delay that explains why he is going after 30 orcs move, 1 fighter stumbled, one wizard whatevered, and a partridge in a pear tree.
