Hmm I wonder how UR can fix this disparity between quality of the packs. Maybe reduce the amounts of credits the other packs are worth? Or increase rarity? Amount of cards? New Blood is just too good.
Inflation and the impact of the wheel is crazy
Now I wonder if pack sales have been down or up since the wheel/BM missions ruined the market.
On topic, my favorite pack is Armageddon. Back when buying cards was the best way to make clintz, there was nothing better than openning multiple packs of them at the same time (during a promo or sale like AAA mentioned) and just scrolling through pages and pages of new cards.
However once I had most the collection complete NB packs became the most practical.
NB packs have always been most profitable. Staff tried putting exclusive cards like griffonmor and enigma in the regular packs to offset this but then they undid it by doing BM missions for nee blood cards. So now NB is king again...
