CleverNickName, between this and the competently designed eldritch Knight you envisioned, you should be working on the fighter.
Also, that's pretty much the playtest fighter.
I admit, I'm not following the OneD&D playtests very closely. The only one I've even read was the "expert" one that dropped recently, and I kinda just skimmed it and made a few notes. Sounds like I should pay a little more attention?
But now that this idea is in my head I can't stop.
Hack Your Fighter
Want to take one of the Fighter subclasses for a spin, but worry about a lack of versatility? Here's a minor tweak that you can make to the Fighter class to make other subclasses more appealing.
This is not, nor is it intended to be, a complete rebuild of the Fighter class; this is just a small adjustment you can make in your home game on an as-needed basis.
1. The Fighter class gains the Combat Superiority feature at 3rd level.
Done. What, you were expecting this to be complicated?
Well, I suppose that if you're
still not satisfied, you could go a couple of steps further but that's a matter of preference:
2. The Fighter class gains the Improved Combat Superiority feature at 10th level.
3. The Fighter class gains the Relentless ability at 15th level.
That's about it. The Fighter gains superiority dice and maneuvers regardless of subclass, and the Battle Master becomes functionally obsolete because it is now part of the
core Fighter class...but that's the way it should have always been from the start (in my opinion).
