I just wanted to hear what you think

Recharge:

1. 1. Regain all expended uses of a class feature that replenishes on a short rest
   2. Regain one expended use of a class feature that replenishes on a long rest
   3. Rogue can use sneak attack 

   At 10+ level, it becomes 2d6
   
   

Example

At the beginning of a fight, the Fighter has 0/2 uses of second wind and 0/1 uses of action surge, and the Paladin has 0/1 Paladin's Smite and 0/2 Channel divinity. 

When they roll for initiative, the fighter gets all uses of short rest abilities (1/1 action surge) and 1 use of long rest abilities (1/2 second wind)
The Paladin has to choose between Paladin's Smite or Channel Divinity to gain 1 use (since they are long rest abilities)

At the beginning of the turn, the Fighter rolls a d6. On a 5 or 6, it can choose one feature to recharge. It regains all uses of short rest abilities and 1 use of long rest abilities/
Same thing for the Paladin, but it must only do it on a 6.

That only works with class or subclass features, excluding spell slots.

Additionally, making all players have infinite hit die, meaning martial are truly "resourceless". 

Finally, I have a homebrew that I like: if you combine your bonus action and movement, you can do an action that is not the Attack, Cast a Spell, or Dodge action. That lets players do their standard thing while having the opportunity to come up with out-of-the-box ideas.
