Yeah, when people complain about the IEDs, it's really the Proms we're talking about. I've got the Prometheus IED disabled in my game and it feels a lot better, because Drams and Phaetons can still be killed before they explode and there's a decent chance of going oh *** and getting out of the way, but the Proms blow up so big and are so comparatively tanky that killing them before they blow up everywhere and baiting them to explode and then getting out is only possible in a tiny, tiny selection of ships and doesn't "feel" nearly as fun to do as it might seem on paper. (Meanwhile, in larger battles, Drams and Phaetons still sneak in enough to cause Enjoyable Havoc, especially if you're fighting with allies and get to watch the chaos without as much consequence.) And then you've got videos of folks like Rarr using a small legion of BombProms to cheese even extremely high-difficulty fights.
It's also frustrating, because logically this is something that should exist in-universe; hell, in vanilla an IED Prometheus was basically what was used to trigger the colony drop that destroyed Mayasura! These are things that would be in the arsenal of a sect like the Path, and even if they aren't in the base game (for reasonable reasons), they're a very natural thing to try and mod in. But the Prom IED definitely feels like a bit of a problem child at this point, and I'm not entirely sure how to fix it outside of just removing it.
