If they can give a substantial enough advantage to it, I'm on board.

I think this would be useful if you have made a tall character with long arms.
If I had a toon like that I could put my free hand on the enemies forehead and keep them at arms length, and try as they might they can swing away but I will be out of their reach due to their relatively short arms.
I could then be free to smack them silly with the mace I am holding in the other hand.
Of course I can see the saltiness already. Forums lighting up with QQ about ZOS developing this in order to generate crown store sales for character appearance changes in order for all chars to have the maximum length arms. The bosmer crew will especially feel hard done by I guess.
