I think there are two different kind of auto concede mode, one is willingly, like I wish to control my rank not too high, such as auto concede after last game is won, or if I reached to rank x ... ; another however, is forced to concede, such as enemy has lethal, or if my hp is lower then 5 and enemy is higher than 25.
So, is that possible to put these two different auto concede into two different categories, it will be much more easier when one comes to evaluate his deck efficiency.
Thanks
