Sorry, but I don't think its fair ... I would accept the decision not to refund, if all players were affected, but in fact only your loyal and supporting customers who did preorder or had a subscrpition were affected because the decision not to charge for training had been made in the time of early access ...
So you punish your loyal customers and those who play free of monthly charge and enter after you patch the free training into the game are the big winners in this ... don't like this decision ... really ...
