However, the AI does need work which it is apparently getting in the add-on. Some of the recent statements by CA about changes being made in the add-on suggest that the battle gameplay is being shifted closer to what these mods provide, although, I'm not sure about slower fighting time being one of those changes. I deal with the poor siege AI by sallying right away thereby turning it into a field battle.
