Ditching the bundle is a good move, as selling players a game they haven't seen without the ability to refund it was a horrible idea. Only issue now is that the change actually increases the costs for existing players who already own all DLC.
Please consider a discounted upgrade to ASA for exisiting complete content owners. If players who already own ASE+DLCs could get ASA for 30/40 bucks, and then Ark 2 for 60/70 then the overall costs would be similar to the bundle but more consumer friendly.
