Q 7: As Targetteer Fighter, from Dragon #310, specifies that one "must making a Full Attack" for Arrow Storm and Sniper specifies "When using the Full Attack option", while Rapid Shot specifies "You must use the full attack action to use this feat", can all three be done simultaneously for +3 attacks at -7 while trading attacks for +1 threat range each? It's obvious that the RAI is for Arrow Storm to upgrade Rapid Shot and be separate from Sniper, but they're choices as part of the same action rather than new actions, so it seems RAW-plausible.
