If I remember correctly, Luffy never really dodged any of Enels attacks he was just resistant to them which forced Enel to switch up his fighting style and attack normally.That's true actually I'm just remembering how fast Naruto has shown himself to be recently. Luffy probably does lose out on mobility but I get the feeling that's not too much of a problem for Luffy since he defeated Enel who moved at lightening speed.
