Lag spikes gotten worse

I've had Guild Wars since the release and my internet connection have never been the best. Never really been able to interrupt good with mesmers etc.
But i noticed that the last months my ping gotten way worse that it been before.

I can get red ping several times during a single RA game.

A wierd thing maybe, might be that I can't cast spells and rubberbanding back but I seem to be able to see everything that is happening around me without too much problem. I see my allies and opponents attacking and casting spells and they don't seem to lag. It isn't the lag where everything stop. It is just me.

Anyone know why this all of a sudden started happening?

Makes it near impossible to play monk for example when you can get "blackout" for 10-15 seconds from time to time or just taking really long to activate the skills resulting in death.

Is anyone else sharing your connection?
If yes do they have a fetish for youtube? (My sister doesn't stay off it, causing me rubber banding hell.)

How does your ping fair on other games? For instance on GW ive never had under 200 ping, on crysis ive never had over 100.

Running speedtests online, do they match what your used to? (www.speedtest.net)

I run a speed test monthly, and mine varies all over the place, one week i can get a seriously bad connection, next month i get a good one, and all this affects my ingame ping.

I was having serious lag issues a while back. I took it to support. We worked for nearly 48hrs and made great improvements. Send them a support ticket.

Well there is my family sharing but they been doing that the past years and it hasn't been this bad before. And even when i'm alone home it is bad. And I don't have ping problems on other games as far as I can tell.

I'll send a support ticket and see if that helps

Support seems to be down at the moment though. Will see when it goes up again.
