WvW fixes
The server matching problem has been known for 3 years. During this time only “fixes” anet has made are about transfer gem cost and locking most populated servers (which players keep complaining about).
If you accept that there are “servers” and each player has complete freedom to transfer between servers, you end up with full servers and empty servers. People will always want to join winning side and in wvw the server with more people will win.
If you accept that some servers have more players and some less, you end up with uneven matches. Only other system would be never change matchups and keep same size servers fighting each other forever. Both are really bad and boring.
Does anyone know if ArenaNet is working on fixing how WvW server matching works?
No. If they are working on it, they are keeping it a secret.
What I fear is that they are busy with raids, and the team is too small to also consider WvW or anything else really.
