In my current game I had occasion to both manually fight and auto-resolve battles vs. Juggernauts armed with guillotine axes.

Manually resolved: the end-result for my army was um... sub-optimal   a 6 unit army consisting of Naddi Arena and 5 spear units slaughtered.

Auto-resolved I lost one 3-man spear unit w/o damage to any one else.

The Jugs are brutal with splash, maul, and axe backswing  (gotta Dodge twice in a row   or die!?!?) really made this current mid-game a serious challenge when I resolved to manually resolve all battles after i realized the battles on auto-resolve seemed strange.  Also good work on fixing the shrink bug, now the Jugs are always a threat full-sized or Shrunk!
