Since i had some Zoro fans complain that i'm not talking about Sanji
I'll bring him up for a bit, as i'm interested of how you woud perceive him and the Raid Suit in that regard.
Let's say we have a Sanji using the Raid Suit for a test run first as he did vs Page One. He does not even realize he is going invisible first, is surprised by the boosters, etc.
Then he get's a bit more used to it and he knows pretty well how to use the basic features at will.
Then he learns maybe little tricks to improve his fighting style because of the extra maneuverability/speed/power he can get from the boosters, or ways to combine his CoA with the fabric of the RS for extra durable defense like Katakuri's Hard Mochi.
Then he learns ways to combine his DJ/HM with all of this, and designs his fighting style to incorporate more and more of all the advantages of the RS. Like a "Phantom" fighting style for the invisibility, something for the superior aerial combat now available to him, and so on.
There's something that the Raid Suit puts on the table, and there's mastery over it and making the best out of it as part of one's combat ability. For example Judge was called "The Garuda" because of how good his aerial fighting style way with his Raid Suit, he had great mastery over that.
So can we use these arguments to dismiss the idea that the RS is a free power up, all the same regardless of what it's user does with it ?
Because if you don't get caught in certain details, is it really that different from Enma in terms of opening new doors and avenues to improve ?
