The point doesn't change just because it was a slightly flawed example. We can come up with the orcs are in the room behind an illusion of an empty room that drops a few seconds after someone walks through the door. Still not the best fictional set-up, but it's sufficient to create a situation where orcs that aren't being stealthy and the fighter are in an initiative situation like I put forth in my other post.
The point isn't the fictional set-up. The point is that 30 orcs can all move 60 feet before the fighter can lift a toe. That doesn't change regardless of set-up, once you are into initiative.
A fighter walks through a 5' wide door into a room and pauses
precisely 30 feet in. Behind an illusionary wall dividing the room are 30 magically frozen orcs, all of whom are precisely 60' from the door, who will unfreeze this very moment. The wall drops, the fighter and orcs see each other. Initiative is rolled. For
any reason that suits us, the orcs sprint to the door first. There are only three squares adjacent to the door so only three orcs can reach them, the rest must extend into the room from the door, probably filling the squares between the fighter and the door.
Your fiction caused trouble for you because it relied on part of the future turning out how you decided in advance. In-world, Han shot first...
the fighter did waffle. Alas, that is what the die roll told us.
Even if I assume a standing start, I can if I am willing include in my
emergent fiction
any explanation - a momentary freeze, a stumble, the fighter was distracted, or whatever - that passes it off. I can worry about whether the fighter ought to have moved a few squares, or I can accept it as a fair - but not precise - representation, and suspend disbelief.
"
Ceci n'est pas une pipe." For me, that must always be borne in mind when interpreting the systems of symbols that we call games. The fighter is
not a fighter. The squares are not locations in-world. There are no orcs.
