You're confused about the conversation.
- The Battlemaster, Champion, and Eldritch Knight are confirmed for 2024 and out the UA stage.
- The Brawler is cut from the 2024 PHB.
- They are stopping playtesting on the Fighter.
- The 4th Fighter subclass has to be a subclass that does not need public playtest.
- It has to be a reprint of a past published Fighter subclass, an adjusted published Fighter subclass that they already have data on what to fix, or a UA fighter subclass that they have data on
- The PHB subclasses were chosen as opposed pairs
- The Champion (simple strategy) was paired with the Battlemaster (complex tactics)
- The Brawler (uses nonweapon attacks) was paired with the EK uses (spells)
- The Brawler is cut from the 2024 PHB.
- The chosen subclass will likely have to pair with the EK
- Out of what is available the best contrasts to the EK is the Psi Knight and the Brute.
