I don't agree with your approach on the Midnight Blade. Also you saying that Chidori is a defensive skill... Like come on? That skill has a lot of damage, sure it has control but that means it's defensive? Sure not. Like you said, midnight blade is squishy so the paralysis that Chidori makes it so that your opponent won't combo on you so even a squishy ninja as midnight blade can tank 1 mystery or 2 without combo following it up. The key thing about midnight is using Chidori before your opponent, paralysing his whole team and if possible bursting down his main or biggest threat with Chidori + combo, in order to accomplish that you need the most attack you can get, meaning you should focus attack on the mood. That's my opinion, if you want to control enemy team and outlast them, you should've chosen Earth Main.
