I'm not going to rejoice for this just yet.

As an East Coast player, I've noticed a lot of times that servers will go straight to the West Coast and usually ping begins to hinder my gameplay. Even with the GCD, I can imagine worst case scenario that it can mess with my reaction time and as a consequence cause me to screw up mechanics, at least with other games.

Like someone said, I'm all for this if gameplay will be better for more customers.
