Dots and SkS/SpS

Leviathan.
If you're too slow, you can't midare before he does the second malstorm.

This is more likely uptime problem than skill speed.

You can also get and extra gcd before he does malstorm for both which is a DPS gain.

Same as above. Higher skill speed will make getting extra shifu easier but that's it.

You comfortably apply your nana before the puddle drops on you as well to get another gcd.

I usually Higanbana after the puddles drop to minimize dot clipping

You can also fit the midare before he drops puddles just before tsu 2, and that's the midare under a pot.

I don't pot at that moment but I can still midare just fine before the puddles drop just before underseaquake finished casting.
