Yep.... this had me a little salty
I swear if Orcs, Redguards and Nords get screwed over I wont be all the pleased. As far as Im concerned, in Oblivion there was really no good reason to choose those races. They inherently had worse magic skills no matter what and all the other races had intrinsic abilities that they could never attain. There was little benefit.
Individuals run at different speeds, races do not. Germans aren't automatically faster than Brazilians. What Skyrim is doing is changing run speed based on the individual (your encumbrance, what you're wearing, probably perks or spells as well) rather than the race.
Id put money on the Brazilian. Regardless your reasoning has flaws. I wont get into a real life discussion although on average I'd say you're still incorrect. Anyways if that is your opinion on running then why are Orcs so strong? Why are Altmer so great at magic? You should also note that Redguards were supposed to be known for their "quickness of foot." Looks like that wont benefit Redgaurd players this time around.
