Latency Problemes

I wrote an email and got a fast and good response, thanks for that! I did everything new suggested there, so the last option was that I should post it here to get technical support.

Hello GGG support,
since the necropolis launch i occasionally run into connection problems, you probably hear this frequently but did every possible thing that got suggested.

First of all it cant be my pc, i upgraded it a year ago and i can run VR and every other game, it worked until this league and everything is updated.

My Internet runs normal as well, discord, streaming or other online games run fine. I already restarted it so many times, it cant be it.

I have zero other backround things running, i even used discord on my phone with my flat.

I used some cmd stuff to clear everything

(this 4 commands)
ping google.com ipconfig /flushdns netsh winsock reset catalog ipconfig /release ipconfig /renew

I used different connections, Frankfurt, Amsterdam, Milan, Paris and London, everything in central europe

I did everything to the controls that i could think of

And now to the real confusing part:

I am standing in my hideout with a latency of 10ms, everything is fine and i can cast without any lag. Then i go into a shaper boss, it went up to 200, just like that. Then it hovers aroung 80-100 but it honestly didnt feel like it. I cant cast spells and everthing is just delayed, macking it unplayable.
So I die, getting send back to the hideout, 10ms.
Then my friend carries this shaper, get out, i went in a cleared shaper map and it just gives me 80-100ms, how?
I mean, i got this new turtle hideout and some people get problems joining it, so i assume it is harder to load the hideout then the shaper lobby.
I play with 2 friends, one of them is facing the same problems as me, one never had such problems. We have the exact same settings, i got slightly better internet and hardware. There is nothing left i could think of.

Is there something you could do to fix it, does it have something to do with the instances? Disconnects resulting in map loss are also sometimes the case, i dont want anything back, i just want to play.

Sincerly
