Guild Wars 2

I just returned to GW2 after not playing for several months. I had switched from an American server to a European server so that i could play with a friend and hopefully cut out lag issues because it had less traffic. on Tuesday, i started experiencing lag issues not only in WvW but also in my story line quests and 70-80 maps. It has become so rediculous that i had a delay for about 5 minutes with no message or d/c. idk what is going on but i am getting up to 90 fps so its obviously network related. Also i have chekced my connection and i am getting excellent signal strength so it is not a personal issue either. someone please lead me to some answers before i decide to pay money to switch back to a crowded American server to see if that fixes the problem.
EDIT: sorry forgot to mention i am currently on the EUR server Whiteside Ridge but i used to be on Maguuma
