Wouldn't spending a GE on WP in the HE city be a strong play, especially for a non-IND, no-stone situation? This is especially the case post-Assembly Line when a GPP farm can run more engineers and WP synergizes with Pentagon particularly well for land units (3 barracks + 4 WP + 2 Pentagon + 2 GG/Theo = 11 xp for 3 promotions out of the gate). Another settled GG or Vassalage and Boudica can build Commando Inf. In fact, Boudica can build Commando Grens if she gets two GG's and a GE early and has a religion. They can then supplement 3-promotion Cuirs built in other cities. Did I also mention the Commando Grens get Guerilla I from the Dun as well?
