Hello Network Admins
As per the ticket logs (i was told you would have access) there is some sort of issue, IMO between the ITALY AWS node and your main EU Servers that is causing lag spikes for skills, up to 5/6 seconds between clicking and the skill "performing", making game play in PoF maps almost impossible.
This is NOT happening in any other map to my personal experience, having invested around 200 hours of game time in the last few months in PRE PoF content on a new char, but the moment i started my quest line in the expansion, especially in Desert Highlands it's present every time i try to play.
I've found a "partial" fix, by forcing the game client to HTTPS (port 443) i get a different IP in PoF maps (/ip command) and it seams to be a some what fix for the issue.
Full logs of my pc, exhaustive network logs and videos are found in the ticket, reply here or there if more info is needed).
It's week 3 of this issue for me and tech support says their unable to offer new help/info still (checked this morning) so "help me network admins, you'r our only hope"
