not sure what you're getting at here...yup some cards do similar things...

The reason some of the cards you mention are better than the others is mostly because, as you say, they are class specific. This means they can afford to be a little more powerful than non-class specific cards with same stats/similar ability, because they are restricted to a narrower card pool. For example if Yari Bladedancer was just a generic Human ally like Puwen it would be too good, and clearly outright better than Puwen. But since it is a Warrior-only card it is fine for it to have the ability, cause there are only the 7 Warrior heroes who can use it, as opposed to the 16 Human heroes who can potentially use Puwen.

To expand on that, some class cards are intentionally better than faction or neutral ones where the extra part beyond whatever they have in common with another card (e.g. Bladedancer vs Puwen) is aligned with a speciality of that class.
