I think it is far safer to defer to Elesa here then it is for us to blow the last Command Seal that we can freely use, 3 years BEFORE the HGW starts. There is too many issues with Fusion at the moment. Fusion without Zelkova is untested and can go oh so bad. Maybe the PoAP will make it ok, maybe not.
Give the second dose of PoAP if you must as long as you keep the 3rd dose for Sion but the Command seals are far more precious than what I think people value it.
