Making flanks select drush+xbows and pockets knights would be easy, but that would cost randomness and Barbarian would become much more predictable, and that's not my goal. However I have planned to make flanks and pockets co-operate more. Barbarian tries to adjust strategy if it doesn't seem to suit properly, but by default it's random. Barbarian is also generally more passive at BF and persians may go elephants there.
Castle age sling already exists, although it isn't very common.
until now we never had problems playing with the AIs on voobly in MP. Good to know though that the AIs could cause some lags, so its not always the human player
@UP:
can i install the UP and still play on voobly? Where do i get the latest UP? also on aok.heavengames.com?
