"as telekom germeny user you cant play half of the day due to packetloss up to 70%"
This may be true for you but is not the case for all in Germany.
I have been playing from Berlin the last 5 years and my ISP is O2 and since we are in Germany we all know that the main trunk lines belong to Telekom.
So the problem could be many things: ISP, Telekom, Internet router settings, PC/Console settings, Server.
IRL I have to actually work with Telekom as they are a service provider for some places I take care of and Telekom can be difficult and they are actually a bit behind the times. How many places within Germany cannot have wired internet because Telkom just cant get the main trunk lines right or laid out.
