Hmm, Interesting Tactic, Wizav85.
However, I have some questions for this tactic:
1. If the AI army have more archers/skirmisher. They'll fire into your main infantry line first. If you start firing ar them from the bushes, they'll switch the target to your archer. Their infantry is on defensive mode and protect the archers from calvary charge.
2. How to kill their Calvary early (even in 1 flank), if they have superior Heavy calvary like the France Lancer, Fatimid's Khanzaki Guard or Mongol Heavy Lancer ? Normally, if AI have superior calvary, they'll advance slowly with their infantry. Right before the infantry engagement, they'll spead out and target our archers and calvary.
