Reduce the potency and recast time on Goring Blade to 20 seconds.

By doing this, this makes each of Paladin's combos 10 seconds.

Royal Authority combo is 10 seconds (Fast Blade > Riot Blade > Royal Authority > Holy Spirit).

Confiteor combo is 10 seconds (Confiteor > Blade of Truth > Blade of Faith > Blade of Valor).

Goring Blade "combo" is 10 seconds (Goring Blade > Atonement > Atonement > Atonement).

This makes it so that Paladin no longer has the awkward 62.5 second total rotation that forces them to basically drop an Atonement every rotation to make sure their stuff lines up for raid buffs.
