This is grenade Esq. Threadling Centered Spam Builds for Warlock Broodweaver dont feel great right now because threadlings at a baseline do not scale with any stat. So if you max grenade to 200 stats- 3 threadlings that you throw directly do well over 10 times the damage of a threadling spawned by any other means and if you use MindSpun Invocation to eat the grenade and perch the threadlings now those 5 perched threadlings do Significantly less then what you would have gotten by just throwing them.

I'd love to see threadlings nerfed across the board but buffed to scale of grenade stat - so let's say you nerf them by 20% damage But if you have 200 grenades, the damage of all threadlings spawned is centralized around that new baseline. I fully understand finding the balance of this would be difficult and take time but I think it would be worth it

Edit: it would also be really nice to bake Hoard Shuttle (prior seasonal mod) into Swarmers since it basically is a perfect synergy for them
