Blood Mage Ascendancy is bad and underpowered

Here after release to voice my opinion about this.
I'm a lvl 50 Blood mage and the ascendancy absolutely sucks, sanguimancy doesn't sustain you nearly as often as you want it to, you cannot pick blood magic, because it makes it so spells cost double the life and i ended up killing myself a few times before realizing it.
The 10% of Spell damage Leeched as life node is not working at all, I'm dealing 25k damage to bosses and I'm barely leeching 100 life, the node that makes you take 25% of damage over time is also very weak and doesn't help nearly as much as i thought it would.

I deeply regret picking blood mage and i hope GGG buffs it in the future, right now it makes no sense to play it. Wish we could respect our ascendancies.

Here is the life cost of some skills if you do pick blood magic:

yeah I'm having a bad time, I really wish I didn't play this character. While I really like my build, I think it can work well, I'm punished for picking the ascendancy and now have to manage both mana and health while losing it just trying to fight a boss. I literally damage myself more than the boss and when I get hit, usually it's death because fuck me for picking the ascendancy.

Unfortunately I agree. The blood mage ascendancy feels like a downgrade when playing it, specially early game when you don't have enough critical chance to proc the passive. What are you really getting in return? Life Remnants to "increase" my max health? Not worth it, specially not against bosses. I had to take off the point from my ascendancy to be able to kill the boss since I was basically killing myself, and it was so much better, so easy.

Can we get something else? Like transform our Mana to Health and remove Mana cost from spells? Something like 2:1 ratio would be great.

I really wanted to like blood witch but it really doesn't feel right.

Terrible design, and to be honnest if i look arround, all streamers are going 2 builds, Titan warrior that one shot bosses and mercenary fire + poison and we can see some range builds but nothing reall impressive.

So we have 2 builds ok great job GGG the exact problem the mock for about other titles.
