What Do You Guys Think About A Gimmick Like This?

So I was toying around with making a gimmick weapon with massive -hp% and -hpr, but insane hp and life steal, and for mages healing is banned while holding it. Basically with the idea being that whenever you hold it your health capacity becomes huge, but you have no way to immediately fill it besides using life steal. However, at the same time the negative regen is fighting against you. Essentially promoting an active playstyle to the max.

Example modified Singularity here: https://wynndata.tk/ci/403663647

In my opinion we need more gimmick weapons because there is so much potential.
Thoughts?

 

In a word: Broken

in a few: Life steal activates on every mob you hit. if you get a crowd up, you can EASILY fill that extra 20k HP, especially with mage's extra melee range, and become nigh unkillable from there, not even mentioning things like greed

________________________________

that said, the idea of just straight up banning certain spells with a high spell cost could be cool for some gimmicky things (like an ice snake/teleport based damage build that has super high spell and base damage but can't cast meteors)

 

Cool idea

But there is a thing called hpr stack
Also lunar spine is somewhat close to this playstyle
