I like that you followed the general path "pattern" (3rd attack power, 6th defensive power, 10th utility power, 14th attack power) and I like the flavor but sorry dude, you're using the flavor to justify that its way overpowered.
For example, your 3rd level power (which I'm assuming is only while raging) grants a flat 6.5 bonus dmg per attack action - the comparable Frenzy power has to use his bonus action to obtain an extra weapon attack and for that he gets a level of exhaustion at the end of his rage (which takes a long rest to get rid of).
In addition, your aura does 2d6 to all foes in 5' and you don't have to take an action to do it. For comparison, the 20th level paladin ability Holy Nimbus does 10 radiant damage within 30'. "Yes, but mines only 5' the paladins is 30'! lol" to which I reply "2d6 is a heck of a lot more dmg to creatures at 3rd level than 10 is to creatures at 20 and the paladin only gets this ability at 20, you get it at level 3!"
Basically you want to avoid the situation where any reasonable person would say "Why bother building any other melee DPR character class, when this one is obviously superior to everything else in the game?"
