My ping is between 310-650 at the moment, as is most everyone from Australia and New Zealand (in all games we play as servers are always opposite side of the world for us). And the game is still playable. AOE's are a bit of a pain, but can be dealt with if you think quick. 150 ping is hardly game breaking. Learn to deal with it and compensate for it.

I'm sorry but I really do find it amusing when people in Europe and USA complain of ping times when us Aussies have been living with it for years.
