Ensuring both the teams playing in an online match have equivalent server pings is one of the primary roles of the tournament admin. In a match yesterday, SK Gaming was forced to play at 80 ms with the other team being at a much lower 25 ms.
ESL is forcing us to play with 80ms while the other team is playing with 25ms and it's a shame kk by cyaaaa

At higher levels the ping matters a lot and considering how close the skill level between teams is, it is quite surprising to see the big difference between the two teams.
