Wow, so many replies. To clarify, i know that (arcane name\helminth ability name\shard name\mod name) exists, but it also takes a corresponding slot in a build, like with any warframe.
And Dantes strength isn't overguard quantity - it's overguard regen and immuntity frames while casting his kit; on higher base levels like 100-300 you need 20k EHP available at all times (close to 3s) to feel comfortable and take damage. I'd like to have Dantes EHP scaled about 30-40% (Shield 250->325, Health 390->500, Armor 145->200 at lvl30), from 829 to 1158 EHP base. Having a gating ability, like with revenant or nidus etc, doesn't mean they should have 1HP at base.
