I believe there should be a westcoast server... First off you have East coast players getting 30 - 40 ping in Chicago and us Westcoast players get a 75-90 ping there. 
You call that central, I think not. 
In my opinion a westcoast server would be nice... they have stronger hosting data bases 

 Like Dallas 
 
  On top of that, east coast players wouldn't have a problem with ping because since Dallas has a stronger hosting data bases then most states they should get no more then 60 ping 

 unless you live out there in the woods with 4g and only allowed 10gigs of internet...

Soo.... Plus one to Namo
