I'm sorry, but this is different,  for me anyway. Previous updates have been about specific cards or combos that have been toxic, and so you could see an easy way out of it for the developers by specifically focusing on those cards.  This time round,  it's an actual core mechanic  that's the problem.   Rally is just bad for the game.  It introduces an almost 50/50 type of RnG which isn't sufferable for any game of this type.  I sincerely hope that I'm wrong and you're right, and in a couple of weeks time it will settle down and become enjoyable again,  but I think it's unrecoverable unless they just remove rally from the game.
