Right now, some executions like Conq's ''Gut punch and Neck Breaker'' and Gladiator's ''Brain dead'' have the effect of destroying/severing heads in the process, but similar executions like Shugoki's ''Burst your bubble'' and Valkyrie's ''Shield Grab'' do not despite having the same concept.

My suggestion is to add the head destroying effect to both of these executions. Valk right now lacks a beheading execution and this would solve her problem
