Just like to share some pictures of the army compositions in early game after first initial turns that show really nice Army stacks!. I understand initial first turns spam lower tier units but this stops at around turn 10 when the AI has forced to recruit better armies.
Arverni Composition at around turn 14 in Grand Campaign
Carthage Army around Turn 15 in Grand Campaign
Cessetani rmy composition Turn 12-14 in Grand Campaign
Volcae Army in Grand Campaign Turn 16
