Some good solution for Blood Mage TUNNING

Hi dear GGG,few days ago i think about BloodMage's OVER DPS and come to good solution for this.Today BloodMage have too much ways to scale his DMG in endgame
without losing in defence(because of spell life leech he got for free).Plus with
new Vaal cultivated uniques his scaling break through the roof and in majority
this is because BloodMage still may keep stacking his mana pool to gain even more DMG and defence(through Archmage,Arcane Intensity notable and MoM passives)
So i think best solution is to change BloodMage's first ascendacy note "Sanguimancy", keep the "Life Remnants" skill but change the first part.
Instead of "Skills gain a Base Life Cost equal to Base Mana Cost" just place the "Blood Magic" keystone.This change stop BloodMage from stacking mana and scale
DMG and defence further and in the same time support the theme of BloodMage who is sacrifice his own blood for the power.






P.S. Good luck with new update guys, you are one of the best game developers of our time))

I'd rather have base Crit chance node removed entirely tbh. Or Spell Leech one.
Both together are just broken.
