Reinforcements delayed?

[professorspatula]

I don't know if that message was replying to mine, it's difficult to know with these forums. But anyway, I let the AI control all my reinforcements. It's an experimental/role playing campaign where I have so many units, I'm not too fussed over how many survive, so I let the AI throw away my units at will. I wish it wouldn't throw all my poor Night Raiders away though. The AI's stupidity during the 'Siege of A Thousand Idiocies' as I now call it, was the last straw however. I'll auto-calc any siege that uses AI reinforcements. If the AI can't even figure out how to use more than 1 piece of siege equipment when it has several, then there is no point in ever playing the battles.

I'm also not convinced by the 'number of fast units determines chances of reinforcements showing up'. When the AI reinforcements has onagers which slows down the entire army, surely that offsets any fast unit status?
