dude, you made 3 trips to Indra, I made well over 20. Your experience is not representative compared to mine, and even mine is not that statistically significant. There's lots of people who, like me, had very few issues attacking titan, so your case is an outlier, not an indicator of a widerspread issue.
My relatively small number of trips does not change the fact that I, and others, experienced numerous issues. My experience is only representative of my experience, that's the only direct frame of reference I have. I've never claimed it to be a wide-spread issue, just that plenty of us have had problems. FDev themselves have acknowledged this fact multiple times though, suggesting
they thought it was wide-spread enough, else they'd not have granted rewards for just being in the area. They knew people were having problems trying, and failing, to engage prior Titans, so they gave the reward for just being in the proximity. I benefitted from this myself for the first Titan. Subsequent Titans I have been able to engage, accruing sufficient bonds, but these were not trouble-free experiences.
I can't explain why some have a good experience and others not so much, that's down to FDev to discover why these instances can go so badly for some, yet be fine for others. I'm
glad plenty of people are having a good experience with Titans, it's fun content when it works. I would likely have done more runs, if the instance wasn't being so buggy. However, once I got the qualifying amount of Bonds on that final run, I really didn't want to go through the possibility of Vents not opening or damage not being counted again. It gets tiresome when things go wrong.
If you only go in open, you may encounter bugged instances a lot more often. I went in PG and only encountered one bugged instance. In solo, none.
I did hear that Open can be particularly bad, so I wasn't in Open. I was in a small Private Group, however, no other members were online, so I anticipated Solo-like performance. I did intend to go into Solo, as advised by other forums member, but I forgot, logging into the PG out of habit. I only remembered once I was already at the Titan, and didn't want to relog only to be booted light seconds away, and have to traverse the caustic region again, consuming more caustic sinks.
Instancing can be very flaky when other players are involved. I myself, as well as my regular wingmate, have suffered issues when someone with perhaps a weaker PC or a poor connection have joined a previously well-performing instance. One player arrives, and they're rubber-banding all over the place, damage doesn't get registered / huge damage suddenly applied and other weirdness. That's just ED for you. Those I've played with directly, on decent PCs (ED isn't that demanding) and good connections just don't see issues. This is what makes the Titan stuff so weird, no other players are in the instance yet I still had issues.
