Syrcus Tower - Major Lag Issue

oh, the weekly reset.
ohhh, new shiny loot in ST.
yay, let's do it!

and here begins the nightmare.

I start casting my spells, and OH, WOW, Astral fire and umbral Ice activates like 2-3 minutes after the cast.

srsly.
we clear the room and start fighting Scylla, and it's still the same. at some point I probably get sucked in by the Void, and i find myself dead.
my bf raises me, and I wait for the raise "cutscene" to jump in.
...no.
I've accepted the raise, but i am still a cold useless body on the ground after 5 minutes.
BUT SUDDENLY. the cutscene start! yay, i can play again!
...no.
another 5 minutes waiting, and I am sitting there, being an invisible and invulnerable fool, who doesn't even appear on screen.

out of frustration, I decide to quit it, because I feel i'm robbing a spot for my freinds, because i can't do nothing.

while my frends clear the room after Scylla, and get to the second boss, I am still trying to abandon duty.

If the first time I played it, I thought it could be because it was the first day after the patch, and everyone was doing it, I kinda expected to be lagging.
but if it's the same, EVERY time I do it, it's infuriating.
I've been lagging ONLY here.

I just want to play and get my frilly Scylla robe ;____;
am i the only one with this serious lag issue?

When you say lagging do you mean your fps drops to a crawl or is it your connection?

I actually haven't looked at the fps, while I am sure I have a bad connection, (I usually download patch and fixes at like 0,17 mbps, it's sloooooow @_@) but I've never had this kind of lag... I mean, rarely the games freezes for like 1-2 seconds while I'm duty, but that is expected, I'm not asking for perfection xD
