GHB 2019 Open Play battle plans

[Tibus367]

A friend and I decided to try the new options for Open Play using the Open Play Generator.  The rules require players to put units wholly within 3" of their "arrival edge" which in my case 18" long.  There is no way even a small force would fit in such a small area.  Large models can hang off the edge but units with larger model counts can't all fit in the area.  Am I reading this wrong?

If you are referring to meeting engagements.... well there is a lot of poorly explained bits.  A small focus group of players would have poked holes all over this new section and GW could have cleaned it up... but it seems they didn't.   So, like the new terrain section, I am waiting for an FAQ for something that shouldn't need FAQ's to use.
