I love hitting graveyards (Sun Shards in T2, Zombies and phantoms faint at my sight) and arenas (though 8 gun puppies dont really help the cause of bombing...) but besides that, what are the most rewarding places to hit?
I've heard that Treasure Vaults are some of the least valuable zones... I don't disagree with the logic behind that.
But then where else would I *Want* to hit up? Clockwork Tunnels? Deconstruction Zones?
