Yeah. This is the story of my pvp fights. I get a bonus action at crucial times, not only with arkwing but others where my bonus action gets passed as if I never got it (despite the BONUS ACTION text…). This doesn’t just happen with my arkwing it’s a recurring issue with my other arks as well. What’s the point in S ranks if you can’t even use your bonus actions…
If your arkadian kills an enemy arkadian that has stun skin, and gets a bonus action, then the bonus action gets skipped, but you’ll still get the text pop up. It’s been designed this way. Are you sure this isn’t what you’ve been noticing?
The bonus action isn’t ‘skipped.’ You have it, but since you were stunned, you get put back however many TU that ark’s death revenge stunned you for. So, say for instance, Arkwing used supernova and you killed a chopper, but got a bonus action. Normally you’d be back 250+120 TU without a BA, due to the stun; however, since you got it and were also stunned, you only get set back 120 TU.
Make sense?
