They are shorter. Therefore, rather than damage-per-turn, it becomes more of a thing "how high can you burst, bro?"
Next up is your best damage in a SINGLE turn, so effectively your Full Burst turn. For whales who slam 2m on ALL Hime, it becomes just a test of how much can you go above the soft-2m limit. Water is pretty good at that, since you slam Sieg-Ea-Oceanus(SR) during Stun.
For us mere mortals, eh, I doubt anything will change much.
