I am submitting this report as a result of a reply I recieved to an in-game report/message I sent regarding this issue. I looked in other parts of forum, couldn't find if this has been mentioned before. Maybe I missed it, if so, I apologize.

I am also not sure if I am filling out this "form" correctly, as several "templates" were provided without much clear info on which one to use or why. It should not be so difficult to submit a simple bug report.

What happened:

During my very first Hydra fight we encountered some sort of glitch halfway through the fight where the boss froze and would not move. This seemed unusual. I asked my party about it and didn't really get a clear reply until after the fight, where an argument ensued about whether we had exploited a bug. I had no idea what to expect, nor did I see a way to leave the battle. They would not stop fighting it. I did stop fighting (after I dc'd and came back), but the fight concluded anyway and I got credit for winning (?). Seems pretty cheesy, as I am pretty sure that is not how the fight is supposed to go.
Wyverns popped occasionally and they kept yelling at the DPS to "kill faster" I don't know if anyone really knew the fight was glitched or not, but I suspect the glitch was forced and that players who abuse that glitch took advantage of us who were ignorant of it. I hope you fix this glitch soon, it ruins the enjoyment of the fight entirely. I feel like I got something for "free" that I don't deserve (the win). Even with all 3 hard primal fights to go yet, this seems like an unfairly easy step otw to earning one's relic.
