As an Australian player I have managed to do Titan HM surprisingly. However, I admit that the game is ruthless when it comes to connections sometimes. Take the last boss of Copperbell Mines for instance. No matter how early I move I cannot avoid the Power Attack, even if my character is halfway to Narnia out of the circle. Now they could have easily put an instant-death mechanic with the attack, and that would have made Copperbell HM untouchable for someone like me (and many others by what I see).

Defend the game design if you want, but as an Australian I CANNOT get a better connection to the servers apart from moving off the damn continent. I will never have the assurance of knowing if I got out in time or not until the game decides for me.
