Two servers only divide people. Creating a server with small rates will end in the same way as with Peace and Evolution. I personally would prefer x5-x7 max but I take into account the future of the server and I do not see the possibility of playing on a server with 300 people.
x10 is a great balance looking at current demand (I mean the list of people online on the home page.).
The lower the chronicle the better, of course without exaggeration - Interlude can be forgiven
GF seems to be an interesting option all the more so that the H5 has very large competitions. At worst, you can always update to H5.
