I have a kineticist and i need gear recommendations for him

Im currently playing an aurabot and i need gear for the kineticist, hes not the greatest because he has a 6 link KB and 4 link kinetic bolt, but after 6+ hours of running maps looking for one i havent found a better one.
I bought a headhunter for him and it makes a great difference, currently i have a piscators vigil on him as well as marylenes fallacy and dawnbreaker for defence.
What items should i give him, and would some rare wand be better than piscators?
Without buffs his damage is pretty meh, his bossing damage is terrible so i would love to take some upgrades for him but i have no idea how their scaling is.

The most interesting options I've seen:

1. Overcap their fire res and use the fire penetration ring. Use flame link and pyroclast mines of sabotage to buff them.

2. Play marauder with one of the huge phys weapons (marohi erqi, winds of fate), "warcries have infinite power" node, and rallying cry. Use grace of the goddess on merc and/or lightpoacher + abyss jewel stacking.

Here's what I'm running on mine:



I use her for more characters, so yeah, not optimized. Though I'm currently running a Bleed build, hence the boots. Clear is good, and her utility is useful.

Mine has a 6L Kinetic Blast, and a 4L Greater Kinetic Blast with added Cold Damage and crit. Hence the gloves.

Personally, I find these mercs tanky enough, so investing in defense, other then capping the resists, is a bit of a waste.

Here is my kineticist:


Setup:
> Gloves + rings = Soul Eater
> Shield = maximum frenzy/endurance charges for me and my animated weapons
> Amulet = extra-dps (lucky damage for my animated weapons)
> Rest: DPS + a bunch of abyssal jewels.

I think the Spirit Charges are just visual, combination with Lightpoacher does not seem to add any damage. But the abyss jewels themselves are working for sure, I can see the stats increase and feel the damage boost.
