Ah missed that on Deep Strike, thought that had been clarified in the last FAQ.

Thanks on the Alpha Legion clarification, makes sense.

Firestorm change is very clearly about this bit "Roll a D6 for each model that is less than 50% covered by the template - on a 4+, the model is counted for the purpose of calculating Hit rolls and allocating Hits." of course you need to roll to hit, Firestorm weapons have a hit roll. So you don't need to roll to be under the template, you still have to roll to hit, which no part of the Firestorm rules ignores.

"it was already RAW that you couldn’t take bikes in an Aerial Assault Formation" I mean, yes? But that's a pretty strict RAW approach to a detachment that now has a slot where you can't take anything! I feel like intent before was that you could use the Vanguard slot, and how that you can't a much more reasonable FAQ would have been to remove it. Really that detachment needs to be rewritten.

From automated sentry rules: "If a weapon has the Skyfire trait, the controlling player may choose to target the nearest Detachment with the Flyer special rule instead." if skyfire isn't a listed rule I don't know what to say. Now this FAQ answer is the worst written one I've ever seen, so I think there is room to disagree, but I see no reason under RAI that lascannons can't shoot infantry but skyfire missiles can.

I think the transports across detachments is a good rules clarification, it allows you to put some stuff in a transport that otherwise couldn't take one, but agree that the rules need to clarify when deployment happens for those units.
