Is your feature request related to a problem?

When trying to maximize recovery of life or energy shield, it would be interesting to evaluate the effect of damage reduction nodes (armor, resists, blocks etc) on the recovered stat. For example, getting more block chance would increase this new stat because each life/shield point recovered will tank more damage on average.

Describe the solution you'd like

I'd like to have this presented as a new stat in the sidebar and the calcs page. The idea is simple (the feature probably isn't!), I think this would do it:

Effective Hit Pool Leech/On Hit Rate
= recovery * effective_hp_per_hp
= (Life Leech/On Hit Rate + ES Leech/On Hit Rate) * (Effective Hit Pool / (Total Life + Energy Shield))

Additional context

No response

Start by tracing how existing Life Leech/On Hit Rate and Effective Hit Pool values are calculated and exposed in the sidebar and calcs page. Confirm how the proposed recovery and effective-hit-pool formula should combine with total Life and Energy Shield; done means the new stat appears in both requested locations with consistent results.
