I farmed 15 in a few hrs tonight (5 per character)... and this is typical, I do it at the end of every season, I always do it in one night. I farm them at different times too... at the beginning (I guess I'll give away a secret) to farm the seasonal redborders... great farm if you want to unlock the seasonal crafts asap. I use them to test efficacy with scaling too. I've been farming and manipulating the rng in this game since D1, there's rules: learn the LS rules. 1. Don't die... (It matters) 2. You CAN do skips... BUT only spawn cancel skips, meaning the enemies or champs don't spawn in or despawn... except I can't think of any current LS with a despawn skip. 3. Kill everything that spawned in before you open the chest - you can nuke boss early - but kill EVERTHING before you open the chest. 4. Let the at least the end mission timer expire & go to the results screen before leaving... this will help prevent input lag or "sync lag". Input Lag can rob you of loot for hrs if you're not paying attention... If you aren't getting anything from the chest... no cores, no purples, no seasonal engrams... you're probably bugged out. To fix this log out, exit your game... relaunch & log back in. It happened to me tonight actually after I switched to my 2nd character. Input Lag can happen anywhere too... if you remember Ketchcrash dealt with it for most of that season, many people were timing out before they got their loot. So, if ever... you feel like you're not getting drops... like none, just exit your game and log back in. I clear my cache too.. but that's not 100% required. I just noticed that some anomalies in this game seem to be more frequent when your cache hasn't been purged in awhile. LS rng isn't that bad on Legend or Master, the difficulty you choose should be based on a number of factors; like I'll use Exodus as an example... I can do Legend in 3-4mins per run without frustration OR 5-6/7 on Master sweatin'... everything teleports around that LS, the shotgun Dregs will blink behind you, above you... the Overloads bounce around everywhere. If you can't nuke those barrier servitors individually right before the forcefield... and they link up, it is madness. So, I run Legend normally when farming Exodus. Other LS's Master might be better... because I can do it almost as fast and there aren't a bunch of unpredictable pain points. Like Chamber of Stars... even with attrition I'll run it on Master. Even if it's significantly harder, if I can get in a flawless rhythm & my times are less than 50-75% more I usually farm masters. If not... Like Exodus because it can be so funky, Legend might be better. If you can't go flawless on Master, if it takes you double the time OR longer... you're better off grinding Legend LSs.
