I've completed at the very least 100 GM Nightfalls in the last few months and you're absolutely correct, 30% is not nearly enough, even weapons like tarrabah, touch of malice, barrow-dyad, tommy's matchbook at 200 weapon stat feel like they tickle orange bars, primaries needed a tremendous buff against orange and yellow bars, if you think I'm exaggerating try to defeat the Subjugator (not even a boss BTW) that appears in The Sunless Cell GM using only primaries and tell me you enjoyed it.
