The hybrid classes are hard to figure out. Take Cunning-Fierce vs Fierce-Resilient, for example. On one hand, cunning beats fierce and fierce beats resilient, so Cunning-Fierce should beat Fierce-Resilient. On the other hand, resilient beats cunning and fierce ties with itself, so Fierce-Resilient should beat Cunning-Fierce.
So you end up with some some Cunning-Fierce dinos like Magnapyritor that are more like a fierce (immune to decel but are weaker against distraction), and others like Diplovenator that are more like a cunning (weak to deceleration but immune to distraction). Since different Cunning-Fierce dinos focus on different things, it makes sense that some should beat Fierce-Resilient, and others should lose to it. As such, I tend to evaluate hybrid class dinos as individuals (i.e. not all dinos of the same hybrid class will have the same strengths and weaknesses). The class almost doesn’t matter, only the moves and resistances that happened to be given to it. As long as every dino has sufficient good and bad matchups, there’s no issue there.
For Poukandactylus, they’ve built it with a mostly cunning strengths so far (mostly dodge and distraction with distraction resistance). Now that doesn’t mean it can’t be made more fierce, of course. But keeping the need for every dino to have a weakness in mind, it wouldn’t make sense to have it be equally strong against fierce AND resilient, even if that’s what the hybrid class suggests: if that was the case, what dinos are supposed to beat it? I guess the obvious answer there is “cunnings” since they beat fierce and are neutral against themselves (and most cunning-fierce dinos like Magna and Monolometerodon tend to be “weak” to cunnings), but it would probably have to lose it’s distraction resistance for that. Then again, Magnapyritor and Monolometerodon have both deceleration immunity and dissertation resistance, so maybe it would be ok (even if it’s probably the most broken thing about Monolometerodon)?
