Personally, I think having Chaos Legion packs in the reward chest will help in speeding up the scarcity of CLP which in turn will make the prices of CL cards to increase soon enough. And if I'm not mistaken, the profit from the Chaos Legion packs will go directly to devs, so if they will allow CLP to be available from reward chest, it is somehow taken directly from their profit.

But of course, we know that the problem they are addressing here is the low sales observed after the general sale. First 6 million was sold in just days, but the rest of the 12 million packs takes too much time. If Chaos Legion will not be sold out, the release of Riftwatcher edition will definitely be delayed.

Hope I win this raffle, my ign is mechababy. Any cards will do :)
Cheers!!!
