It seems that many players enjoy games with standard AI, which was not intended (former intentions were to provide training opponent or a quick mean to test decks). Currently the player's score is not effected by AI games, because players are forced to play in friendly game mode.
I wouldn't like to mix player's score obtained from games with other players with score from AI games. Therefore I suggest to add a separate win/loss/draws score for AI games excluding AI challenges (EXP will not be effected still). This will not disrupt the AI's role of trainer/deck tester, because players will be able to choose if Friendly game mode will be active or not.
What do you think?
