Cross-Server Dungeons Laggs

[Qwetro]

I was playing all CBTs and didnt had any problems with ping,everything was smooth and playable,even now since start i didnt had any problems with questing/map dungeons,but after going to cross server dungeons it started to lagg so bad that i had freezes sometimes,mobs and players were freezing for 2/3sec from time to time and it was impossible to play,after finishing the dungeon(somehow) i left the party and tested it in the Cross-server dungeon place with storage/marketplace etc. and it was lagging too,my LMB attacks were lagging like i had 400/500 ping,so i left and went to the normal maps and it was fine,so i tried in the cross server again and it was the same,laggs everywhere
 
any1 have this problem too?
