-Do you feel this way about dodging (tap) or just general boosting (hold down)? or both?
It has more to do with when you cancel an animation using Boost which you will be doing VERY frequently which consumes 50% of the boost gauge and then restores slowly. You get 5 Normal dodges which seems fine for me and just holding the button barely consumes anything in my opinion. As for suggestions to alleviate my personal gripe it would be to slightly increase energy regen, or if you want to further introduce part stats make it a bonus on say, the light parts to offset its low Armor.
