Are Bug missions on Difficulty Level 4 Cursed?

Been playing some lower difficulties lately to farm Super Credits and I’ve noticed that the spawn rates on Difficulty 4 bug missions are insane.
It seems ridiculously easy to get stuck in a breach loop and the patrols are constantly spawning out of nowhere.

If I drop to Level 3, it’s a cakewalk, step things up to Level 5 and the spawn rates seem way relaxed, just with bigger bugs.

Attempting a Level 4 results in the squad constantly scrambling to navigate the map, and kill counts from 500-800 per person if we try to 100% the mission and visit every POI because the breaches just open up right on top of the objectives and POIs preventing us from completing them until they are clear.

Even playing with my regular squadmates who run Difficulty 7, 8 and 9 with me agreed that the Level 4 operation we completed felt like it had Level 7 or 8 spawns just without the Bile Titans or Chargers.

What’s your experience? This is just an unusual observation I’ve noticed over the past few weeks. Don’t get me wrong, I love blastin’ some bugs, but Difficulty 4 feels way out of place for some reason.
