The crafted set is decent.

Not really worth the gold, imo.
But if you want it, or have it, it certainly won't hurt.

Just run as many BG's as you can stand; AV is the best.

The Titansteel Mace is a fairly decent main hand.
Or the ToC dagger.
Either will last you quite a while; stick the 50 SP enchant on it (63 SP costs a ton).

Do Wintergrasp at every opportunity.
The quests do a hard reset on server maintenance.
And you can do them four days after you did them last.
So potentially twice a week, if you do them within a couple of days of maintenance.
