Lag 10 char

Since the maintenance/restart i have been getting some crazy A lag. Feels like i have 4000ms.
For example;
LFR Wing 1 I get lag
LFR Wing 3 no lag,
LFR Wing 4 i get lag
My FPS is 100 , MS is 30 (normal for me)

@Slickers your no the only one my dear . when im on oceanic realms no problems 60ms ping 50ms home thats normal when a friend and i was in a dungeon on USA realm the ping went too 5000ms and only 50ms home .its blizzard .the realm merge
