To add, it's sort of a waste of momentum if a dodger guards and they end up evading, so they only hurt themselves if they guard and manage to evade.

It's not a waste when the guarder is able to compensate for two forms of offense-- autohits and hit checks. It's a maneuver that isn't so much a waste than a safety measure. There are always circumstances (not even including team battles) where turtling can work in your favor, especially when you time shenanigans like EI. Gaining up to 70% DR and retaining your full evasion seems much more silly. Either way, the numbers are arbitrary, and with this suggestion, if someone wants to have their 10% DR, they can have it, but it's going to cost them.
