There are people who will play mostly against bots, and you don't want them to lose all the time.
I think we managed to avoid that problem
But more seriously - it would be nice to have much better bots, and just let you pick a level.
It would also be nice to have a little bit better bots, because now the bot is doing some really awkward moves.
The main problem here is development time. So far I've been able to spend 1 week on setting the AI up and 1 week on strategy, which was just way too little to get a grip on 300+ cards.
I hope we will find much more time to work on this in 2017, and when we do creating the possibility for others to write bots will certainly be part of it. Not because I think it will save time, but mostly because it could be a lot of fun for people to write them and see how they play.
