You'd be able to save the time it takes a nerve impulse from head to hand that way. It's not much but apparently it can be significant enough that in some DotA games shorter players are disproportionately successful in the roles requiring the fastest reflexes.
Is that supposed to be a joke? DotA doesn't rely on reflexes nearly enough for that to matter.
Data doesn't lie.
When so many player play a game, even an almost irrelevant advantage can tip the scale.
Or maybe it's a sociological factor, not a phisics ones.
But the data doesn't lie.
Sure, data doesn't lie, but where is the data? I'm a pretty seasoned DotA player myself and this is the first I'm hearing of any such phenomenon. I can't think of any hero that shorter players have been more successful on than taller players, or vice versa.
