Martial Class Rework Rules

These changes are all in addition to the features these classes already possess and aim to make the latter levels of DnD 5e more balanced.
==Barbarian==
===Rage===
Starting at level 1, In battle, you fight with primal ferocity. On your turn, you can enter a Rage as a Bonus Action. While Raging, you gain the following effects if you aren’t wearing Heavy Armor:
*You have Advantage on Strength Checks and Strength Saving Throws.
*When you make a Melee Weapon Attack using Strength, you gain a +2 Flat Positive Modifier to the Damage Roll. This Flat Positive Modifier increases to the following amounts as you gain more Barbarian Levels:
**Barbarian Level 1: +2 Rage Bonus
**Barbarian Level 5: +3 Rage Bonus
**Barbarian Level 11: +4 Rage Bonus
**Barbarian Level 17: +5 Rage Bonus
*You have Resistance to all instances of Bludgeoning, Piercing, and Slashing damage, including Magical.
*If you are able to cast Spells, you can’t cast them or concentrate on them while Raging.
Your Rage lasts for 1 Minute. It ends early if you are knocked Unconscious or it your turn ends and you haven’t attacked a hostile creature since your last turn or taken damage since then. You can also end your Rage on your turn as a Bonus Action.
Once you have Raged the Maximum Number of time for your Barbarian Level, you must finish a long rest before you can Rage again. You may Rage 2 Times at 1st Level, 3 at 3rd Level, 4 at 6th Level, 5 at 12th Level, and 6 at 17th Level.
===11th Level - Bloody Temper===
Starting at level 11, while in a Rage, should you be struck by a Critical Hit or are dealt damage equal to more than Half of your Current Hit Points (Minimum of 2), you may make a Single Melee Attack at the attacker without expending your Reaction. 
Alternatively, you may choose to make a Thrown Weapon Attack at the attacker, even if you don’t actively have the Thrown Weapon equipped. If you are dealt damage that would otherwise leave you Unconscious, but not Dead, you may still utilize this ability.

Whenever you hit a creature with a Melee Weapon, the creature takes an Extra 1d8 Radiant damage.
Whenever you perform a Divine Smite through the Divine Smite Feature, the Damage Dice you roll for every Spell Slot Level you expend in its usage becomes a 1d12, instead of a 1d8. This effect also applies to the Extra Damage you roll against Undead and Fiends.

Additionally, when making Melee Weapon Attacks, you may choose to replace one of the Melee Weapon Attacks with an attack from an unequipped Loaded Ranged Weapon or Thrown Weapon; doing so does not remove the currently equipped Melee Weapon or Weapons from your hands.
