I’ve run them over 30 times recently in 10-12 run sessions. While it’s nice that they spawn almost every time and drop 1 or 2 items almost every run, I’ve yet to get a class mod from them since the rare spawn event. In the recent 30+ runs I’ve seen 10 Vanquisher, 6 Thunderball Fist, 6 Nova Berner, 3 Hyperfocus XZ41, 3 Surge, 3 Tran-Fusion and 1 Star Helix.
Have legendary class mods been removed from their loot pool or had their chance to drop been reduced? I don’t recall seeing anything on it in the Hotfix and Patch announcements.
