Jesper, you are forgetting that trial accounts SHOULDNT even be playing seriously. Stefan aims to have everyone to pay for their game... Trials shouldnt have any advantage at all, not even a minor disadvantage. Every distadvantage should convince them to pay. The way you describe it the trials would think something in the direction of:
"Oh! I can get rewards without paying, kickass!"
Imagine when WoW decides to let the trial cards be implemented in a real account over and over again, free WoW? -_-
