If you make it work like an ER, the VR may not be as useful as it first seems, as expenditures from the pool would have to be conscious decisions, and attacks would usually be targeting actual HP.

The huge problem I have with the "objection" is that's not a property of ER, that's a property of FP, which ER inherit from. VR inherits from HP, and is an analog of ER, not a descendant trait of ER.

(EDIT: OR if you're using a multiple-inheritance language, there's a third class: "Reserve", and VR is a descendent of HP and Reserve, while ER is a descendent of FP and Reserve. Either way, the core functionality of VR is defined by what HP does, not what ER does and therefore what FP does.)
