When adrenaline first came out, Zanz ruled (correctly) that certain abilities were overpowered when combined with adrenline. These included poisonous touch and devourer.
But when fractal came out, Zanz ruled (incorrectly) that fractal devourers was perfectly balanced.
So what gives! Why is it fractal devourers, a card which allows for 8 times the devourers, is less powerful than adrenal devourers, which only allows for four times as much stealing. Their quanta cost to reward is almost exactly the same, and in fact I would say that an adrenal devourer deck would be equal to a fractal devourer deck if this nerf weren't in place.
Seeing as everyone's got their heart set on fractal being balanced, why can't adrenal devourers get four bites of the pie?
It's only fair...
