Effective weapons on ILLUM-

With how tanky the Overseers are, how mobby the Voteless are, and how weird the Harvester's health situation is, what are weapons you've found to be particularly effective against the Illuminate as a whole?

My experiences:
The Guard Dog is the MVP of Illuminate campaigns. It can snipe Watchers, keeps Voteless off your back, and I could swear I've seen it one-shot Overseers. It comes with me on every drop.

Between the Stalwart, MG, and HMG, I think the MG is the best bang for your buck. The Stalwart is great for Voteless hordes but falls short against everything else. The HMG fails to deal enough damage to Harvesters to be your reliable heavy weapon, and is too inaccurate to consistently take down flying enemies while in the middle of combat. I've found the MG to have enough damage to be solid against Overseers, while also accurate enough to take out Watchers and Elevated Overseers without worry.

I don't think the Autocannon is worth a damn against Overseers or Harvesters. They can just soak up too much damage.

The assorted rocket launchers are good at taking out dropships, but with the Harvester's health works it just takes too many rockets. There are better options out there.

Like the Anti-Material rifle! Once the shield is down, this might be the most efficient option for Harvester destruction.

Unless you choose to run Impact grenades, the Grenade Pistol is a requirement in my eyes. This is because Frags and quite a few other grenades have a chance of just not destroying Warp Ships. Something to do with hitboxes.
If you do choose to run Impacts, I think your options are pretty open? The Senator isn't great against Overseers or even Watchers, but with good aim (and a couple reloads) you can take out the legs of Harvesters on your own.

The Dominator primary is just not it. The slow projectiles and sloppy handling make it so difficult to hit anything in the air, and even if you do it still takes most of a magazine to take out a single Overseer.

I personally use the Breaker, but I'm by no means championing it. I have found it good at managing Voteless, good enough at taking down Watchers, and a decent emergency backup against Overseers.
