How I would change action surge, cunning action, haste, and the bonus action spells.
Action Surge
Starting at 2nd level, you can push yourself beyond your normal limits for a moment. On your turn, you can take one extra attack on top of your regular attacks.
Once you use this feature, you must finish a short or long rest before you can use it again. Starting at 17th level, you can use it twice before a rest, but only once on the same turn.
Cunning Action
Starting at 2nd level, your quick thinking and agility allow you to move and act quickly. You can double your speed until your next turn.

Haste
3rd-level transmutation
Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a shaving of licorice root)
Duration: Concentration, up to 1 minute
Choose a willing creature that you can see within range. Until the spell ends, the target’s speed is doubled, it gains a +2 bonus to AC, it has advantage on Dexterity saving throws, and it gains an extra attack on each of its turns.
When the spell ends, the target can’t move or take actions until after its next turn, as a wave of lethargy sweeps over it.
