Not easily but you can. You win the same packs that can be bought. Is it slower, yes, and you pay for it that way. Some games you cannot progress all the way UNLESS you pay, which is not the case here. They are going to sell 900,000 beta packs for $2 each. You want them to sell out asap, because that means more money for contests, but ridiculing a minor bonus when you may not realize they are trying to incentive the very top to keep pushing once they reach the last level or for other reasons is a waste of everyone's time. Just my business pov 2 cents :-)
