Energy Blades should increase maximum energy shield leech rate by 100%, minimum

Maximum total recovery for Life is 20%. Maximum total recovery for energy shield is 10%. Blood rage degen is 4% of Life and 4% of Energy shield per second. If Life and Energy Shield is the same, Blood Rage results in (10-4-4=) 2% maximum Energy shield recovery per second. If Energy shield is half of life, Max ES recovery is less than Blood Rage degen (10-(4*2)-4=-2).

This has been a considerable problem for me trying to level as flicker strike energy blades elementalist (besides flicker strike being bad to play with less links to begin with). Investing in ES, supposedly damage and mitigation for Energy Blades, is only damage since I can't leech it beyond blood rage's degen, which is necessary for flicker strike to work while leveling. Unless I go raider for Way of the Poacher. This means I have no Energy shield at all.

Now I can fix this by investing 4 points into ethereal feast and a point in leech mastery to add 100% increased max rate, as well as investing in some recover ES on kill, but that's more investment out of damage or mitigation that could simply be on Energy Blades to take ES max recovery to parity with life max recovery.

I want to play this particular build in PoE and I'm really not enjoying trying to make this work, to the point I might just drop out of the league before maps.
