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.
Mercs rules the terrain spreads out to allow whoever is there to fit. It doesn't make them able to maneuvre at peak capacity but it certainly enables them to spawn and not instantly die. ---
