And with regards to the creation of air and such, the issue isn't whether or not the armor COULD do it, it's whether or not it is, and you never said it was. Coming in after the fact and saying "oh, it was doing this during your post so your move is invalid" doesn't work unless it was specified as doing that (whether in a prior post or as a standard operating procedure in a CS), or is commonly understood to be the way things work. For instance, I don't have to write my character breathing in every post, because he's more or less human and that's what we do, but I would have to write him holding his breath in order to avoid a poison gas attack. What I couldn't do is say that he's been holding his breath for three posts if no mention of it was made in the previous two.
