Ok, so just to understand, this is what I'm gathering in terms of combination using the "true" values.
Height "True" Value | Weight "True" Value | Movement Speed | End-lag / Cooldown | Landing Lag | Character (Hitbox) Size | Range | Attack Speed | Jump Height | Weight (Heaviness) | Sword Size*
Short | Light | Fast | Low | Low | Small | Poor | Fast | High | Light | Small
Short | Normal | Fast | Low | Low | Small | Poor | Avg | Avg | Avg | Avg
Short | Heavy | Fast | Low | Low | Small | Poor | Slow | Low | Heavy | Long
Normal | Light | Avg | Avg | Avg | Avg | Avg | Fast | High | Light | Small
Normal | Normal | Avg | Avg | Avg | Avg | Avg | Avg | Avg | Avg | Avg
Normal | Heavy | Avg | Avg | Avg | Avg | Avg | Slow | Low | Heavy | Long
Tall | Light | Slow | High | High | Large | Great | Fast | High | Light | Small
Tall | Normal | Slow | High | High | Large | Great | Avg | Avg | Avg | Avg
Tall | Heavy | Slow | High | High | Large | Great | Slow | Low | Heavy | Long
*apparently sword size doesn't matter anyways in terms of range, so just a visual stat
Now, this is where it gets tricky for me: the "true" values are just the two extremes and the dead center. Are there basically more combinations in between these values that slightly differ?
This is what I'm iffy on myself. Although the differences might be small, as soon as you start changing frame data (such as landing lag, cooldown, etc), you're changing the timing of punishing, reacting, etc. This stuff is very important in high level play, and with so many different "in betweens" that could be created, it seems extremely unreasonable for players fighting Miis to take a quick look at them and know what would combo them, punish them, etc at certain percents or wtvr. I'm not presenting this for the sake of being annoying, but it is a concern that I know many other players will have.
Don't get me wrong here, I've been playing the Gunner myself and have really warmed up to it, personally I see no problem allowing all their alternate moves even in a "non-custom" meta (fairness is a dumb argument), but changing stats around like that... that's a whole other cow to milk.
