Well in all reality we have many various ways of warping around currently, it would be quite nice if it were all made into a single easy access point of sorts. The fact we have all of these ways to get around that are spread through the world seems fairly annoying. Is it a pressing matter that must be addressed? No, however it is nice, and between all of the various warps we currently have, we really should not need any more in the present areas in the game as we can get to basically all of them in some way, many of the we can get to multiple entrances or locations within them. The only real improvement that could possibly be made is to put them all into the same system so that they are more easily accessible.
