I've done my best to answer RJM's questions below:
1) Elephants: The rules account for Howdahs, but NO LIST in the AOA book lists them! Which armies historically had Howdahs and what would the point costs be??
A: Woops - I forgot about that! In this case you'll have to let history and the model you are using be your guide (i.e if the model comes with a Howdah, then it counts as having a Howdah). No quickly scrath-built howdahs please! Having a howdah or not doesn't change a units points value.
2) Chariot Generals: Most of the classic chariot armies (Trojan, Persian, Eygptian) whos generals usually rode into battle in chariots, are now easier to wound then the chariot drivers!! Under the test lists the Generals (all have base toughness of only 3) would have a +1 to Toughness when riding a chariot. The crews still retain this +1 toughness. Is this intended or an error?? The hitite general starts with T-4 so is not affected.
A: This is intended. Basically, generals who I think should be good at hth fighting already have a high toughness and attacks, while those that I see as being more skilled and shooting etc don't. Thus Hittite and Trojan generals will be more likely to get stuck in, while Egyptian and Persian generals will be more likely to stand off.
3) Massed archery: The test lists did show which armies were allowed massed archery, but this stipulation has been dropped in AOA. Are we to assume that all mixed formation units are now allowed to use massed archery?? This would make sense.
A: All units can make use of massed archery if any models are equipped with bows.
