What feels odd is that they couched it in the phrasing of 'better metagame' by allowing the choice, when they've outright stated the old one had some weird interactions they wanted to outright fix; the Blinded Pilot critical being key among them.
It also means that the reprints of the old box set won't be getting the new decks in them, because this phrasing means that it's a choice rather than simple obsolescence.
Had they phrased it as "We get it, not everyone has it, so we're allowing the choice for the meantime", it would have felt more honest while still moving forward. The claims of good-for-the-metagame they've made? I'm not so comfortable with it.
