I have to agree with both Rom and Pera here. Too much of the "mystery" of random rates. 150 gran should get you minimum a 3 star 2 x 2 stars and 2x 1 stars. Even at that recycle rate which is below 50% BTW.
You reduce the cost of the pack 20% then up the rates of gaining a some other chance of getting a higher card but overall the recycle rate looks poor. Meanwhile gold boxes are still in their usual overpriced state. Might as well bring back that 12 dollar 5 star lotto ...
Seriously though why are the recycle rates such a low proportion to the initial pack cost? Why are their not purchasing options other than playing russian roulette with your money in regards to the randomness of the lotto? Give your spenders options and they might well spend.....just saying.
Nought's had, all's spent, Where our desire is got without content;'Tis safer to be that which we destroy Than by destruction dwell in doubtful joy.
