Lags and freezes on hots only

Hi there, i am having issues with lags only with hots, i already opened a ticket on the US forum by mistake as i am an eu player, and followed a bunch of tips but it has been a month now and i have still no improvement and nobody is answering my previous post anymore. Can anyone help ? Steps i did amongst others> I tried deinstalling and reinstalling the game, i updated my drivers, and i tried other blizzards games - they work perfectly - as well as other mobas such as lol which also works perfectly. I ran a test using Win MTR as suggested by a GM under a similar post in the US forum and the dxDiag.
I got a feedback saying connection was going through us servers which is strange as i select europe region and play from europe, maybe it’s coming from there but how can i change it as i select region and i dont see what else to do.

Please help. It really affects my playing experience for more than a month now.
