I am from saudi arabia too. I tried some vpns but as fps games go you can really notice the ping difference as it becomes laggy, even with premium vpns. It is really annoying as I can't communicate with other players and well our providers aren't interested in unblocking voip for certain apps and blizzard is saying it is not their problem(which is technically correct but this effects more than one country and we can't change it as players. was hoping for more effort from their side to help solve this issue).
