I like Xeno’s idea of gnashing fang combo/burst strike granting stacks of continuation. They’d last like 20 or 30 seconds and you consume stacks of continuation to use jugular rip/abdomen tear/eye gouge/hypervelocity. Then if you need to double weave cooldowns you don’t clip your gcd or lose any of your continuation skills. Also, make double down cost 1 cartridge and increase the duration of no mercy.
