We already know what this can buy.
Overall, a bad change. First, everybody who wasn't playing SB now will, so people who only do that and maybe are not the best will get the sh!t rewards. No way I get Elite with everybody grinding SB for the 400 tokens. Second, just tokens... really? SB became a bit more enjoyable for me since there was the TOTS pack. Now it's back to crap. With 200 for SB, and the 200-300 a week for the objectives (hopefully), that's at most 500 a week. Over 5 weeks. The best rewards are 2500 tokens. But that's ONE reward. A month of grinding for ONE card?! What a promo...
