As the only real way to level after 400, the +3 prime engram has horrifically low drop rates. & I know mythic story is supposed to drop power, but right now it's bugged & dropping at 300. Since I hit 400, on Sunday, I've run around 150 portal activities, all Grandmaster, getting A or B+, mostly A, every time & I've received 2 prime drops, I've had a run of 67 & I'm currently on a run of 72 with 0 drops, I'm playing all day for absolutely nothing. People can only take so much of being unrewarded before you lose them, & these drop rates are actually not acceptable. I've seen creators saying it's 1 drop in 20 portal completions & maybe it's been heavily nerfed but I'm not even getting the 1 prime a day drop from the old system, but this is apparently better? I enjoy grinding, I enjoy levelling, but playing as much as I am, got nothing, yeah not acceptable to see number go up.
