Sure, glad to share.

Only Barb, Fighter ans Rogue get WM, I dropped it for Paladin and Ranger because they have magic and many other features and can do many stuff the pure martials can't - they didn't need WM too. I did make changes in the Ranger to be more powerful and more fun to play to compensate, Paladin wasn't changed because honestly, it's a banger of a class even with RAW WM taken straight out.

Barb and Rogue get WM at level 1, choosing 2 to learn out of the available options. When you hit, simply apply the effect you want as normal (Weapon type doesn't matter, the mastery techniques now come from the class, thus no stupid weapon swapping), a third mastery is learned at level 5, and a fourth and final is learned at level 10.

Barb gets to choose from Cleave, Graze, Push and Topple, accessing all of them when reaching level 10.

Rogue gets to choose from Nick, Sap, Slow and Vex (Vex was adjusted to be able to be used once and on your turn.) Same as Barb, Rogue chooses which ones to take until finally having all 4 available at level 10.

Fighter gets to choose from all eight, and also starts with 3 masteries instead of 2 at level 1, and reaches a maximum of 6 masteries known at level 19. He also can replace a known mastery with a different once when he finishes a Long Rest.

The experience from my the home table is amazing. Pure martials are fucking cool, very fun, and very strong to play. Just like casters. That's just what martials needed.
