600 Blacksmithing - Now what ? A few questions.

[Ebonheart]

So well after returning to the game since Cataclysm, I decided on Enchanting and Blacksmithing as my two new professions. I managed to level both of them to 600 early last night.

I was wondering what do you have to do to learn the new patterns for BS? I know that some of them are locked behind the Klaxxi which I am working on and will pick up in due course. I've picked up a single 450 ilevel pattern from the BS trainer in the Shrine to level from 575-600. But then, what about the 522 epic patterns, and the PVP pieces. How do you learn them?

Some are also learned from your daily Lightning Steel Ingot cooldown.

Basically what Zulandia said. When you craft a Lightning Steel Ingot, you get a random pattern that you don't already have. This seems to mostly be PvP patterns for now. But sometimes you get the new 522 crafts as well. For comparison I've made 14 ingots and have Tank Helmet, Tank Boots and DPS boots patterns.
