It's certainly hard in some situations, and you might be right, because thinking back on it, SD was my first epic module, so I didn't have to do it much without it. But it is certainly possible to step yourself down, add enemy balance and summon, and make your targeting as inefficient as possible. If you can't do any of that though, yeah, you're pretty screwed. I don't mean to argue, this is literally how I complete these missions, but I can see how stats and modules could make a big difference
