I appreciate the ability to test-play the new cards against a bot before another player, but it would be nice if Lord Rat would actually purchase/play any of the new cards against us - so far I've played 3 straight bot games where the AI completely ignored the new cards (never even made use of the free starting favor).
Unfortunately, getting the bot to buy and use the cards is something that needs some time and finetuning, which is often not done (if at all :( )until after the release.
