Ideas and suggestions.

Let me put it more clearly. Why is quickly capturing the max-crypt on the first day, losing a couple of units in the process, thanks to a clear understanding of the strategy, NOT considered an exploit, while capturing the Factory is? Is it because the Factory gives 5000 gold, while the crypt provides troops? Are troops always more important than the economy? Okay, then.

Well, comparing 5k gold and 2-3 giants in the early stages of the first week is a bit of a stretch. People also mentioned graveyards, and I don't like how easily they can be captured either, but I think graveyards and necropolises are not comparable to a couple of giants. Moreover, graveyards and necropolises can be captured with almost any castle, unlike the Factory.
