Just got out of a group from Frostvault where literally every mechanic on the vault protector was broken.
Orbs did not consistently kill spheres when they exploded, laser phases were basically a roulette (had a couple pulls where we burned it down to 90 then had the laser, then seconds after it unshielded there was another laser phase immediately with 4 lasers), the number of lasers after the first one is seemingly random, lasers were going through the boss shield and wiping us where we were on the correct side (in a way that was clearly not just us being too close to the edge of the shield), spheres continued to spawn way faster than they used to (we had like 3 of them spawn withing 10 seconds a couple times), lasers phases went clockwise instead of counter clockwise a couple of times, boss just reset while players were still alive, and of course the visual boss shield disappeared forcing us to guess where the edges of the shield were.
How is this boss still so bugged? I submitted like 8 tickets (one for each issue since they don't give you enough space per ticket to say everything that doesn't work) and others in my group sent tickets as well but clearly if all of the tickets players have submitted till now haven't gotten them to fix it then these tickets will mean nothing to them. I've cleared this boss a few times, and every time is was just RNG as to whether the mechanics worked as intended or if we just got wiped by some BS that could not be anticipated as proper mechanics can be. There is a reason many people like myself choose to just avoid this dungeon most of the time, and its not the difficulty; its the fact that you can do everything right and just continually die to BS bugs. Other dungeons at least you can out dps certain mechanics that might be broken, but not when you have mandatory shield phases that force you to endure so many bugs.
I don't know whats going on behind the scenes at ZOS but ever since this last 'phase one of the performance roadmap' the issues with this game has just exploded, not gotten better. I COULDN'T EVEN FISH LAST NIGHT because the lag was so bad in overland that the fish had escaped before the rod indicated that they were hooked. That is, when I was able to actually log in and not getting booted every 5 minutes along with half of the players on NA servers. Is this the kind of performance EU has been contending with for a while now? If so the future of PC NA appears equally bleak. Obviously these issues are much more important than a single dungeon which is why I have no hope the bugs in this fight is going to be fixed any time soon.
The crazy thing is this isn't even a base game feature that happens to not work, this was a DLC that many people paid for that is just broken. You would think that new features that bring in revenue would be a priority for ZOS to fix, but I for one am not giving you any more money until you fix the things I have already paid for.
