Disagree. As in, if we define "fan" that way, we have made the term obsolete, so it's not a useful definition.
Everyone has their own definition of a fan layout. I'm promoting this particular one that I find very useful:
A fan layout is one where: "Most of the shots in the layout are low-to-no risk"
What makes a shot low-to-no risk?
1. Hazards (Posts, Targets and Toys) are far away, increasing your reaction time on the ball
2. No Pops or other active toys/cellars have the ability to fire the ball directly SDTM or to an outlane
3. The shot takes the ball out of play via: ramp, lane to upper pops, toy, or scoop and returns it directly or almost directly to the flippers in a predictable manner (that is easy to trap.)
"FANNIEST" OF THE FANS LIST
Shots are far away and generally low risk in nature:
T2, STTNG, DM, NF, TOM, AFM, SS, MM, MB, CC, (and most modern Sterns.)
It was discussed at length in this thread, but by no means is the discussion ever "over"
