Australian internet can be very frustrating sometimes. It's sad to think that there's a slight handicap when I play Grandmasters and there's literally nothing I can do about it. Before someone says "just finish the turn early", yeah nah it doesn't work that way. It spikes.
I lived in Adelaide from 2003 to 2008 ... WoW launch years .... trust me; I feel your pain. I really think your situation should somehow be factored into matches.
