I have been meaning to do this for quite a while and as i have yet again managed to acquire 20 credits, I found myself in the shop looking at packs. Now perhaps someone knows why, but is not the Rainbow pack useless? I mean, let's think about this logically. It's worth the same as the classic, which let's you thin out the herd so to speak upon the clans that you would like to choose. While, the rainbow pack pulls from all the clans and the number of cards you get are the same. Meaning you have less of a chance to get what you want, at the same price and at the same number of cards...this is. There is no guarantee that you will get an uncommon or a rare or anything, so why is the option even there? Anybody know? If so please post, if not, let me hear your thoughts.
I wouldn't trust any of that. Way too shady and they always want a phone number, address, insurance info, car info, email address, credit card and what not. It's not really free and it sucks compared to saving up some change and just purchasing credits yourself. They also "revoke" said imaginary credits if you are not really interested in what they are offering. It's a money scam, don't do it.
