Lag/Delay in game

[extery]

Whenever I play I get these delays/lags. It looks as everything freezes in place for 1-2 seconds. My casts are completed but not actually casted, people start running in one place and so on.

I usually start off with around 10-15ms but then it goes to an average of 100-200ms and when these delays occur it can jump even higher.

My internet is decent and I was wondering what could be the problem? I was thinking that some closed ports could be causing a problem but I don't know which ports you use (If you can tell me which ports to open I'll be very thankful!)

Same thing is happening to me and a few friends.

It happened also to me in Desolace yesterday and with some delay on casting spells. Maybe it will be fixed soon.
