I dont know if I am the only one with this issue, but whenever I log in since I joined a guild everything stops and lags for 10 sec after that it runs smooth, then suddenly a guild mate decide to change channel and I get huge lag spikes everytime someone changing channel in my guild. I heard rumors from a few other players that they have same issue and they had to leave guild to participate in budokai and even dungeon runs.
I just wanted to address the issue and I would like to hear about others that have same problem or something that is relatable.
