"The very tipping point, you say? It could be wonderful, but not too wonderful. Typically, larger organisations will be able to field a larger number of explorers at any given time.

Something could be found in those structures, I suppose but making those items so strong that they are the "tipping points" is quite overdone, don't you think?"
