Look

Server 1 has 5 top guilds
and maybe 3-5 more that are becoming competitive.

The problem with competition in the servers is 2 fold
1. it costs 150 gems to change realms. -
2. more and more new servers

reduce the cost of to change realms to say 50 gems and servers 1-10 will have new life in GWF. Because then the biggest of the smaller players could move to the same realm and challenge one of the top guilds.

slow done server growth and possible merge some of these newer servers and everyone benefits. The merged servers get new life and pepole may spend more money.
