good point. i'm not buying either. i did my budgeting and realized all the things i could have bought for the amount of money i spent on BD and SM. and all the tokens i bought for BD just disappeared because they can be used and are effective for one round before everything gets erased, while all the tokens spent on SM, all the stuff bought with them gets nerfed and becomes useless with the intention of making players buy more.
so, it was a huge waste in both cases. except for i don't regret spending anything on BD.
