It's not about one or two quanta being an issue, it's about them being more than almost any other quanta creature, meaning it must have a worth to make up for that. A tiny bit more survival ability seems like enough but, without that, no element with its own quanta creature would ever have reason to use this.
That is what balancing unaligned cards is about, IMO. Making them somewhat inferior but still far from unplayable, no matter your element.
