Better Rewards as You Progress or Pay

I’ve noticed lately that the chance for rewards has been lacking, including for the paying side when it comes to shop. The concept is simply, as you level, as you pay, as you progress. The reward types should progress as well. All too often when paying for a box there are less Rare and Epic components and instead more Common ones. It’s one thing to just take something wasted and use it for an upgrade. Yet players want to feel rewarded for their efforts either in progress for a campaign, achieving a new level, or even progressing through an arena battle. Either way if their isn’t a descent reward? Then how is Tacticsoft living up to LAG aka Life Accompanying Games. To me this isn’t something I want to be accompanied too if it means feeling like the effort and progression was all for nothing.
