Sure isnt. Shadow Dragon Kick is worth about 18% and i think heavy punch into Shadow Firecracker is like 14% or 15%. Main difference, like you said, is youd need a dragon to continue juggling off Shadow Dragon Kick, whereas you can one-chance the heavy punch > Shadow Dragon Kick for something like 30%.
This is somewhat true, if were talking about combo opening damage and you have dragons stocked. But that’s a ridiculously hard and situational hit to land raw. I put my findings up in the Kim Wu thread awhile back. Sure you can hit juggles afterwards somewhere in the 75% to 80% range, maybe better.
Omen and Kim have a cute thing where (and i know its a situational opener special…) if he crashes Shadow Orda Shield into Shadow Firecracker, she can get a 23% unbreakable opener. Thing is, it ■■■■ near tops off the KV meter; youre forced into one-chance at that point.
