As far as I’m aware, when you seal twist command you can’t get the other seal to proc on both the white and yellow hit. If you swap to SoC it procs off the white hit and has to be timed at the end of the last swing. If you swap from SoC you might get something if you time it right a little later without a bar.
That is the issue. Seal twisting has always worked best when you swap from SoC because it’s the only way to get the second seal to proc on the command proc. Classic makes this interaction impossible. A clarification from blizzard would be great as missing out on that double SoJ proc chance and that extra SoR damage off the white hit minimum sucks.
