Sorry, I don't know if there's an area for specific card AI feedback, so I just dropped this here. I've been working on druid with a reasonable win ratio, however the bot never plays Ancient of War well. There are two choices, +5 attack, or +5 health+taunt. I've seen many times where the taunt would have saved me, and then I'd have lethal next turn with combo. However the bot ALWAYS, and I mean, literally, always, 100% drops Ancient of War with +5 attack, which is really only a good thing to do if you have a pile of taunt creatures out. Can we look into that AI a bit?
Try to use the new HSBCombatViewer to search for such fights and show it here ... I think it will help the developers to resolve the issue ...
