Rabbit's Revised Fighter for 5e

A personal revision of the Fighter for 5e. The changes are based mostly on my personal issues with the class, as well as the general playstyle of my own group. This revision might not be for everyone, but I hope you can find something interesting in it.

Main changes include:

• An expansion of Fighting Styles into something closer (but not exactly like) Warlock Invocations, allowing for a wider customization when building a Fighter. Styles have also been specifically curated to include more non-combat options that still feel close to the existing Fighter chassis.
• A new Weapon Mastery feature to help sell the idea of Fighters as "masters of arms". This feature accompanies a revised weapon table, including new "Exotic" weapons - weapon variants and more unique weapons (including the already extant Hoopak, Double-Bladed Scimitar and Greatbow, as well as firearms) that only Fighters get default access to. These exotic weapons also give some use to the otherwise mostly useless Weapon Master feat.
• Base class Crit Range increases, to put an end to 3-level Champion dips for extra crit range and instead incentivize sticking with Fighter.
• A reworked Indomitable, now serving as a 20th level capstone to encourage Fighter survivability.
• Extra attacks more closely aligned with other class damage progression (i.e. Extra Attack (3) moved to 17th level instead of 20th).
• An overhauled Banneret to cater more closely to the Warlord playstyle, including the ability to have other characters make attacks in place of your own.
• An overhauled Battlemaster, which switches between Stances, each with its own benefits and drawbacks, and which does not use limited resources. Switch between stances with impunity!
• A reworked Champion, which focuses a little more on athletic expertise, and brings in features from the UA Brute to help sell the raw power of the subclass.
• A tweaked Arcane Archer (renamed to Spellshot) which is no longer limited to only using bows! Magical cowboys rejoice, you can finally reflavor Curving Shot as the bullets richocheting at improbable angles!

This version of the revised class has not yet undergone playtesting, and may be changed in the future. I can't guarantee balance.
