While the number of hits doesn't change, you have to remember that the animation of the Goblin Punch is not that fast. So if you start with a normal hit and then use Goblin Punch, it be faster in real-time. I would even try to open with X-Fight and get a luck start saving turns.
If you're interested, I could give it a try on the GBA and elaborate a TAS to see how fast I could finish him.
There are problems with normal hits:
- Back Row dmg is half (to protect from Dimension Zero)
- Evasion 20%. That's quite a lot - even single miss will mean longer fight
- Defense 100. That mean that only Ultima can do around 5k, all of the rest will do 2k or less, so total max dmg of 1 char will be less then 7k (if you don't miss), while all of the rest will go around 4k, which is far away from desired 8.5k
Rapid Fire (X-fight): Risky business - this fight has 2 extra invincible/untargeting participants. In the second part they are not present, but he starts with protect which half the damage.
Anyway, YES I would love to see your suggestion on video samurai goroh. Even if you don't mind one with average luck and one with luck smiles on you :)
P.S. Did you guys see the unique Dimension Zero? You will not see it anywhere else.
