Hey.

I think, the most valuable "sub-stat" for 2H Rage is the damage.
Really, Your guy trying to hit first and he trying hit hard (as an ideal -- one hit for whole health pool of an opponent).
Your guy trying to maximize the damage. But not something else. Let's help him.

If You agree this idea, next step:
What gear type provides the best damage bonus?
Obviously, it's the weapon.

Proceed next, if You agree...
The best method to buy BG-weapon is the method to buy it for BGP+Trophies.

// Also, there is some sort of ... feature around calculation BGP while You already bought something during season (Nate forbids me to say the word "bug", so i've say what i say).
// This "feature" allows accumulate BGP faster. But still not enough fast to buy 2H weapon for few seasons.
