As far as I can tell it's not an RTS. RTS games are about base building and large scale unit deployment where things like missing aren't factored because it interferes with player strategy and the faster nature of the game. This is compensated by units having dedicated counters and being more effective in certain situations. From what they've said, this is more about individual engagements between small parties, like in XCOM or Fire Emblem, where you have to manage the individual skills and capabilities of your characters.
