I've been purchasing more than 15 boost to Kingboost cause they are the cheapest... But on every single boost I had, I had some problems ! None of them went good from the beggining to the end. And with P3 of SOD, it's even worst. Boosters just have to play till lvl 25, after that it's Incursion from 25 to 50. So at 50, you get a naked character, with NO runes (not event the one you get at lvl 2) and no money cause the booster took it to sell it and make double profit... Well, If you just want to lvl up 1-50 go for it, but if you need a descend character at lvl 50, forget about it !
