I have succesfully used the Winds, Ebon Escape approach. I'll attach the screenie. However, and I say however because there is a little issue with this approach as mentioned by wesman. Opponents DO indeed run to the other side of the wall. They seem to do this only once or twice though and instead of re-zoning to spend another 100g on trying again. Stick around hugging the wall facing the arena and wait....simple
It was happening to me a lot (the running away) and I was getting frustrated and started looking stuff up on the internet whilst still in the tourny, this meant that whilst fighting Razah (who runs away, as do; Alesia, Little Thom and Xandra in my experience) I stayed in tourny but started browsing for a couple of minutes. When I came back to GW, he was trying to out-stare me through the wall and seemed glued to it too. I had an easy time wiping him away with a load of Mez hexes. Same applied to Alesia, who will still run away but come back just as Razah did in the end.
I guess this approach is never going to win any speed records.....
