He lives In Quebec, Canada. People speaks French in america too (just like people in brazil who speaks portuguese instead of spanish)

And the servers are located in Montreal, Quebec, Canada. So he is even probably closer to the servers than most people.
I live maybe 1 km away from the servers, i get 15-25 ms of ping, wich is really good.

But as a tank, I had the same issue as OP on Brayflox's_Longstop, at the dragon Aiatar.
I get out or the AOE he does in front of him, but it still get hit.

With trial and errors, I have found a "solution" : continue to run even if i'm out of the red Area. It's a bit of a mess because he can then move, but it's the best solution I have found so far.
