Re Pikes vs Mongols: Having tried a few more (and against catholic foes) you seriously need to keep the square (or hexagon) or have a few heavy inf/cav behind.

The AI does attack from the rear if he sees it undefended and then you have real problems. So it may seem like a waste of pike (they'll do nothing) but actually it isn't.

I know you guys all know the tactic, just pointing out the AI isn't quite as stupid as I thought (in previous post). Ah well, still a use for all those hospitallers...

(p.s. does everyone know you can get the chapter house in cities too? That is *very* useful...)
