@Ghiblee It would be nice if you can address this issue or at least update the situation where the developer/quality/network team are aware of this problem and trying to identify the root cause.
The past week has been a hell week for hard will. My party failed 3 times and I know of another party that failed 2 times this week. We got frustrated and ran normal will instead.
The lag caused many deaths that's not supposed to happen, for example, will pushed me to a web after I dodged the first leg during phase 2 segment test, segment test at ~xx:36 (considerably late) for phase 1, ethereal form not registering on the server side, boss lag and random tornado upon game catching up with lag, delayed spider leg at phase 3, and probably more deadly mechanics we can't dodge because of the lag. I have more examples of lags in Hard Lotus and Hard Lucid but I think the ones I mentioned for will should be sufficient to demonstrate the impact of lag while bossing.
We are aware that due to covid-19 there are a considerable amount of returning/new players so the server might be under huge amount of load all the time. However, it would be important to note that the players who are running hard bosses in Elysium are getting frustrated.
