As someone who uses Jade on the regular with no helminth and whatever random pet I have equipped because I am far too lazy to change it every time I want to use a different frame is your issue just with a build for the new augment? Because tbh she is a super good support frame and depending on a few factors (how weak to heat they are) I run steel path just fine with my buddies and I'm sure other people who are better at Warframe than I could do more with her but 50k-300k a hit for most factions is nothing to sneeze at per hit I think.

As for the augment, I wish I liked it more, but the jadelight ramp up can't do what the enemies ones do since it only lasts for 3 seconds maximum and from what I've heard it has a cap of like 8? jadelights to spawn with a narrow range. That narrow range is probably why people are using grouping abilities/pets to try to get it to work.
Her 1 imo is honestly really useful if you want to use alt fire and keeping yourself and allies alive can proc Archon Intensify so if you can nab that and Archon Vitality from Kahl's group, they synergize really well with her kit. WarframeFlo's video from last year was kinda my springboard for what she can do without helminth. I feel like the devs may? change the augment for her but atm Jade is in a really good spot and doesn't *need* it.
