Lag issues means new content is worthless to me
Please put resources into reproducing and verifying the unacceptable lag that has blighted new content ever since Dyna-D (specifically when you added the rank meters for R15-25 gear).
This seems to be an SE server side issue, whether it's processing power, network throttling or just too much trying to happen at once.
Dyna-D lag: 1-2s at least on every run
Odyssea A/B/C lag: 1-2s at least on every run, can be worse
Odyssey Gaol lag: 1-2s lag for some characters, 6s or worse for many others
In Gaol I can reproduce constantly a 1-2s lag for 1 of my paid accounts, whereas I get constant 6s lag on my other account. On the very same computer (full logout and log back in as other char). This is not a client side issue.
My suspicion is something in the code for keeping track of Rank item progress is the issue in Dynamis D (since that's exactly when the issue started for me). For Odyssey and Gaol I have no idea what it is you're doing that's so different from the rest of the game that causes constant network response latency, meaning some actions are not displayed on the client or shown in the log at all.
Please investigate as a top priority. I would be happy to help in any way I can.
