Eldar is really good at melee. Last time I played he had better connection than usual (200-250 ping which often spikes to 400 ping) and was playing on melee alt wrecking the server.
Many Russian players are playing on shared connections, from college dorm, which by definition means unstable connection not suitable for online gaming. High ping is less than an issue, you can get used to high latency if it remains stable, actually it is possible with training to adjust your play style to latency if it remained stable. Which usually doesn't because cheap cRPG servers historically had routing issues unless you lived close to server locations. I used to have incredible issues with EU servers but not often and most of the time my ISP was a little bitch when it came to routing traffic to NA servers.
For smooth online experience you need around 30 ping or lower without jitter and that in cRPG was only available to north western Europe. Cologne residents in particular had most stable connection to cRPG servers. Players from Italy, Portugal, Spain and Greece had massive connection issues in cRPG.
