The only problem I have with it is that I really like my Chicken. It is 1 bcx card and I use it often. And it woud be very expensive tu get it to lvl 5 so I can get full rewards in gold with it. So should I not play it and maybe not win because of that? I also have 1 bcx axemaster and I would love to have it lvl 4, but it is too expensive for me. I also have few other cards at lvl 1 which provided full rewards when I bought them and at the time of purchase I did not know I will not receive full rewards by using them.
So I am not completely happy with this change, even though I mostly support it.
