Last, but not least, as part of this update Soulbound Reward Cards will now be able to be burned for Glint at a rate of 10x the card's Collection Power, and Gladiator Cards will no longer be able to be burned for DEC, but instead for Merits, at a 1:1 rate.

We should be caution about this dust system. If most of the players burn the excess bcx of soulbound reward cards, how does a new players enter the game after the next set of soulbound reward card to obtain the out-of-circulation soulbound reward card?

Even when soulbound reward card can be unlocked at a cost, there will not be sufficient bcx to meet the demand of new players. If new players can not obtain a card to be competitive and having fun in the ranked play, they will quit the game.
