So he's giving a completely different ruling outside of the topic?
What I said is that the terrain starts combatants at ten meters' distance from each other - then the Arwings the W100 have gained put them in the air and perform all appropriate modifications, which I interpret as putting all the Arwings at a distance of ten meters from the enemy team. To me this means either all the Arwings in a huge line (with the terrain tweaked to accomodate this) or all Arwings placed at a ten meter distance from the enemy team in three dimensions (meaning Arwings behind, in front, straight above, etc.). To me there isn't a conflict between 'nearest convenient spot' and the terrain starting points, but if there is one the Arwing writeup would have primacy. It's not a ruling.
You cannot fit 100 arwings let alone 40 arwings in a 3d surround at 10 meters. It is mathematically impossible. ---
