I'd do Not So Secret JP over and over instead of this tbh, and I'm not a fan of that JP at all. I have parked a character there, and I know it can spawn from the defense event. For instance I wouldn't have had a problem with a low percentage chance drop from a mob. It's predictable, even if it will take time. I can farm said mob when I feel like it. Compare it to the collection for Aurora and the item you get for using your glider skills in Bloodstone Fen. I've had absolutely no problem with it, even if I've tried to get that item for well over a month now and I still don't have it. This feels more like a prison. There's only a 10 minute window on the event, it's not an event that happens on a timer (atleast not to my knowledge, would love it if someone knew a timer for it) like the Quaggan event where you can just check back after 20 minutes or do Jormag if it's suffieciently upscaled. For this one I have to "babysit" the event or risk missing it, and there's added rng on top of it, and a large part of my frustration comes from that it's removing my joy from the rest of the design/story to getting this legendary weapon. It was a nice different experience compared to just throwing xyz items into the forge like with the 1st gen. legendaries. It might just be me that don't like to play this waiting game spiced with a healthy serving of randomness, but it probably isn't, which is why it would help to get some clarification as to why this is designed this way. I struggle to see any positive sides to it.
