Hello i'm from Brazil and i am having these desyncs for months, i couldnt find a solution, then yesterday i started recording tracerouts, i noticed i had 1 to none packect loss when all is good, but when desyncs starts server loses a bunch of packets (around 10 every 2min or so). im using winmtr 32bit, to game server (145.239.161.30). I only play on Onyxia, but happens on other warmane realms i tested. At this very moment, im having desyncs and 100% disconects after a desync. Yes it happens on server side, as some ppl already posted, i also play on others pservers with normal latency and 0 desyncs/disconnects.
