This game's premium card packs are a huge swindle!
1) There’s no indication whatsoever in the game of which cards belong to which set.
2) The screwed up concept of “sets”. I wouldn’t define a pack that gives the same cards with a chance of a few (less than 1%) additional promo cards as a different “set”. That is extremely misleading.
3) The description of the Pro Booster says “Eight random cards from the professional set with the increased drop rate for ultra rare and promo cards.” For anybody with a regular concept of “sets” this would imply that by buying pro boosters you won’t get standard set cards and vice-versa.
Where I come from, that is defined as shady business practice and I feel completely ripped-off by this whole thing. If I had known about any of this beforehand I wouldn’t have bothered spending a dime on this.
OMGWTFFFS, we see you’ve purchased three Professional boosters (they are listed in the forum thread you started).
All these cards can be found in professional boosters ONLY. You CANNOT obtain them from standard ones.
To prevent future speculations we will add set information to the card details window shortly.
