More battle, rage and spikes in Battlerager

The orginal battlerager seems realy underpower, especialy with flat bonuses, now he can scale, also I tried to mantain the spirit and most of his abilities because the idea of pissed off porcupine is pretty neat

And I hope it's still balanced compared to other subclasses

Battleready

When you choose this path at 3rd level adrenaline surge makes you always ready to trample anything on your path. You can ad bonus to initiative equal to your rage damage mod., additionaly, when entering rage as BA you can also: dash or make one additional attack.

Spike up!

Beginning at 6th level you gain proficiency in smith's tools (or another tools of your choice if you alreardy have that).

Also, when you finish long rest, you can modify your armour with smith's tools by adding spikes to it, choosing one of following effects (you can have only one at a time):

More spikes - you add bonus to AC equal to half your PB (rounded up and doesn't stack with magic armour with bonus to AC, you choose higher bonus)

Sharper Spikes - you can use your armour as weapon - you can use BA to bash enemy with it to make one attack, dmg equals 1d4 + str mod

Longer spikes -  whenever a creature within 5 feet of you hits you with a melee attack, the attacker takes piercing damage equals to your PB

Any damage dealt by this is count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
