Mana cost multiplier of blood magic proportional to new HP

Hi,

I've noticed that since the patch (which overall I am VERY happy with), the mana multiplier of blood magic gem proportional to my now lower life pool (I went from 4300 to 3300) seems very expensive. I regularly find myself on lower amounts of life than ever before, specifically when not taking damage.

In other words, a 6-link ROA skill group that used to cost 131 (hp) mana to cast now drains 4% of my life each time instead of the previous 3%. At 4 attacks per second, and with less life regen due to the smaller HP pool, this decreases my survivability by a considerable amount.

This small 1% difference seems to add up pretty fast, especially since ROA now hits less targets overall (less opportunity to leech) because of the bug fix related to targets having moved out of the AOE attack range still being hit.

Is anyone else experiencing similar issues?

Cheers,
Ross

Also power of Life Regen nodes should be greatly incrased to compensate lower HP pool. If patch was about incrase value of armor, whye blood magic/HP regen was destroyed ?
