Poisonous concoction mana problems

Is it possible to fix my mana so that I can attack more than 2 times before running out of mana with 6 link? With -mana cost of non-channeling cost on both my rings I can attack three times with a 5 link dendrobate. Is it normal to just have to mash my mana flask all day because it feels pretty awful. Also any other tips to help make my build better would be appreciated

reserve less of your mana.

alt quality GMP(anomalous) helps a ton as well.


PS my profile is public, you can see what I am doing as well, I never have mana issues, no need to sacrifice damage for a lifetap either.

im using life tap support. Go take a look on my character items and tree, you may come up with some ideas.
