Concept Help - Swashbuckler and Corsair

[Khaalis]

I've been working on Light Fighter (Fighter Variant Class) and toying with how sustainable it would be and what subclasses work with it.

Currently I think its a valid idea for those who:
a) want a light or no armored fighter that can still fulfill the fighter roll without having to be a plate wearing tank.
b) want to run settings where heavy fighters don't fit in well (high seas, renaissance era, etc.).

For the Light Fighter I'm currently looking at the subclasses of: Brawler, Duelist, Gallant, Musketeer, and possibly a Fighter-based sailor such as Buccaneer.

I had two others, but I am now looking at moving them to rogue: Corsair and Swashbuckler.

So what I'm looking at right now is making these subclasses of rogue focused as follows:

* Corsair - some form of sea legs / athletic focus with some MC Fighter aspects, probably critical hit focus.
* Swashbuckler - focus more on abilities like Cutting Words mixed with mobility features like fast movement, deflect (dodge) missiles, etc.


What do you all think are "key" abilities for two concepts?

Not sure how much this will help, but I created a 5e class based off the 3e Warblade. It is designed to use lighter armor than a typical fighter in exchange for greater mobility. There is even a subclass that can get by without any armor.
