More productively, upgrading your dodge sounds like it risks falling into the same trap as Adaptability in DS2. It's pretty easy to get accustomed to a given dodge timing and iframe window, so if an upgrade changes that, it can be hard to adjust. That said, it's not like there's no precedent for that, with the various weight classes and the Dark Wood Grain Ring in DS1, so I'm sure you'll get used to it.
