Im on east coast, Gustin server, im not sure if this is the only east coast, but you should look at the ping on servers status how i did it, the lowest ping is best for you. Hindi & dev, are both close in ping, you're going to also notice it does not matter much as many servers are populated by players all over the world, so you may want to research the servers history and read some of the threads on there forums to see if you can fit in well with the population.
