What you need to do is respec the ghost tree and remove the top tier (tier 6) skills. That entire tier unlocks higher quality items which either aren't in the beta or aren't in the game, so you end up getting electric center.
oh yeah i see, i read about that in some guides actually the skill gives a 60% higher chance to get the card
and when you ace it you have a 90% chance to get the card
that explains a whole lot...
gonna remove that skill and sty from it until after beta lolz
