So besides the positive stuff like octagonal garnet, there's way too much negative stuff.
Idk if your experience is similar but I bet it is. Here's the list:
1. This event is forcing to run daily trains (all dungeons from Drowning Deeps to Stonescale Passage), and guess what. 14 days of daily trains and the only loot "we" have got was... DD outfit, and literally nothing else. Cool, right? Let's continue.
2. I've opened the trove 182 times without keys, and all I've got was... oh wait, I've got NOTHING! Really worth the time to relog and open it on all characters, right?
I've also opened the trove with 20 keys, and what did I get? TWO legendary elements for a price of one (wohoo, 5g saved), and AN OUTFIT crit so I could salvage it and make just a few gold by selling fabric. 14 freakin days of opening this thing over 200 times on all characters just to get NOTHING. Cool, right? Let's continue.
3. I've ran RT 80 times solo (more in F8 thanks to daily trains) and TS 70+ times solo (more in F8 thanks to daily trains), and guess what... yeah I've got 2 RT psyches during one day, but TS dropped ZERO psyches. Cool, right? ZERO OF THEM in like 90 runs, what the hell is this? How can one augment some items if this crap isn't even dropping ONCE? Let's continue.
4. I've been autofarming this new Ebon thingy for several days. First day I've got THREE chests during that day from a small spot with one scorpion boss. Another day I've got TWO chests within 5 hours from a camp spot with one "terror" boss. What bothers me then? I've just spent SIXTH day on a spot with TWO bosses, that's like 60-70 hours spent here... and I've only got ONE chest after 60-70 hours of farming on a spot with TWO bosses... what the hell is this? The better the spot the less chest % chance or what? Let's continue.
5. The new raid is around the corner (2 weeks to go) and... I've got 4 roses two days ago, and also 4 roses week earlier. Cool, right? Is this how it's supposed to look??? Let's continue.
6. I've finally collected my first 8 purple unity stones and was able to get the very first attempt to make a yellow stone with "very high" chance. Guess what, 8 purple turned into 1 purple. Amazing, right? Very high chance btw!
7. Last thing that I want to mention here are... 130 LEGENDARY JEWELS that were ANNOUNCED in the PREVIEW of PATCH NOTES, and they are NOT IN THE GAME. 3rd week of this event will begin tomorrow (middle of it), and there are still no jewels. What the hell are they? I bet it's one of main reasons why people even bothered with this event, including myself.
Here's the proof and link to the source that they have announced 130 jewels to be inside, but they still aren't: https://www.bladeandsoul.com/en/news/forgotten-souls-events-preview/
I've reported this issue on this forum (screen below), Reddit (screen also below), and Twitter, and @Cyan answered to first two (also below) writing that they will verify it with their development team (aka give us hope). After two weeks there is still no word about missing jewels from their side, so I ask you @Cyan, dude, where are our legendary jewels? How long are we supposed to wait? Was it another bait or what...
I hope your stuff was much better during these 2 weeks, because mine was obviously disgusting as hell, feels like everything is rigged and nerfed to the ground.
