In addition to its current perks, anytime you give a teammate or you gain woven mail, you spawn 2 threadlings at both your and their location. Additionally, whenever you sever a target or rapidly land 9 crits, you spawn 2 threadling at the targets location. Finally, the catalyst now consumes 25 ammo but let's your next shot fire a tangle. Wherever the tangle impacts, it leaves a grapple hold. I think these changes would greatly improve its function while adding more strand synergy.
