Strongly disagree. It's important that there be some incentive to building up your forces to take on stronger enemies.
Agreed. If emblem crafting offers no control over the finished product then you're better off doing any tile given even a vanishingly minuscule chance to acquire high level tanks or emblems.
When they originally mentioned crafting I was pictured something that would let you re-roll one of the secondary modifiers on an emblem, or make a duplicate of an emblem you already own.
Devs need to put more consideration into game system design.
