Is the Elite Trainer Box worth it?

The 9 hits of Steam Siege (Double Rare and up) are worth $181 together; the five most valuable make up 92% of that, so most boxes miss the cards that carry the value. Buying the single card you want is usually cheaper than opening for it; see the Steam Siege chase cards.
