Hmmm, wouldn’t that make Chrono Killer and Time’s Up monsters become much less useful? I mean, Scorpiogeist can get one-shot by Chromera’s Chrono Killer but Toxic Killer fails to one-shot it most of the time.
Maybe what we need is more passives that deal with Stun. We have Stun Immunity, Counter and Converter. There could be:
• Stun Resistance (mitigates the effects of Stun)
• Stun Barrier (gains a shield whenever stunned)
• Stun Reflect (stuns the enemy by a corresponding amount, but doesn’t count as a Stun skill, else it would be very easily exploited by enemies with Stun Counter)
• Stun Deflect (divides the amount of Stun received among teammates)
• Stun E-Converter (increases the amount of Energy Charge by one instead of getting stunned)
• Stun Capacitor (increases the power of the next attack instead of being stunned)
Likewise, there could be some burden passives that instead make a monster weaker to Stun to counterbalance his theoretically OP moveset, like Broken Heart.
