Same issue, also playing from Germany, also with Telekom, pings between 400ms and 18000ms. Leveling and farming, as well as dungeons barely doable. Sometimes with extrem lags, haven´t tried raiding yet, since i expect it to be a nightbare.
same here unplayable 2500-3000 ms and also some game functions stopped working like raid frames
nterfact/frameXML/options.framelua:111 sth with a nil value
Makes it hard to heal when u got terrible performance and game functions from menu tabs not working.
How can that go out like this i wonder. Maybe there is a reason nobody touched the quest log in so many years and maybe it was not skill but sense for risk reward that made them not do it.
My friends are now using a VPN and finally after weeks of heavy lags, they can play with a constant 60ms. Both have Telekom as their ISP and are now using Proton as their VPN.
