lag problem only in cross server dungeon

[Kehldar]

Hello,

as the title say I have a serious problem of lag only when I join the cross server dungeon mode. I have low ping in dungeon joined from the site, quest and even arenas but when I go in cross server dungeon I don't manage to land a single hit. I asked to my team if they had lag too , and asked in faction chat the same but in both cases it appear to be just a my problem and no one else have noticed it. 

I have no clue about why it happen, any help would be greatly appreciated. What can I do to fix it?

thanks in advance and sorry for bad english ;) .
