I think people are looking at the Grand Chariot finisher the wrong way, think of it this way, the last time he used it was before the time skip when he used it to hold the Oracion Seis in place while he was using Sema. So in the time skip he has simply improved himself to the point of one of his more standard attack can one shot a spriggan. And if Grand Chariot has improved this much over the time skip i cant wait the see Sema much less any other true heavenly body magic spells, cause lets be honest this is not or is anywhere close to Jellals last fight :)
