Loranus,
If you look at the question that starts with "Can you take a Drop Pod with a 10 man squad...", and then read the answer, it says "...squads that are placed in reserve may not break down into Combat Squads".
While the example in the question is for 2 very specific situations, in my mind, the answer tells me that "All 10 man squads in Drop Pods that are placed in reserve can not break into Combat Squads". One can even further extrapolate that this only affects Drop Pods coming down past Turn 1. As per rules for Drop Pod Assault, half of your Drop Pods (rounded up) all come down on Turn 1 (which don't count against what you have in Reserve). Going by RAW, I can still Combat Squad on Turn 1 from out of a Drop Pod, since technically, these aren't coming in from Reserve. Any Drop Pod with a 10 man squad coming in after Turn 1, would then be subject to the "No Combat Squads from Reserve" rule.
I guess the debate can go either way, depending on how you look at it though. I had actually heard of this prior to today, but didn't actually look it up until now. Again, it's not the biggest nerf (assuming it even is one), but it would be nice to have clarification. You'd think that with an FAQ, they'd address this... *sigh*... Gotta love GW for being so clear...
