I'm a solo player who played in a same server(SOS) since 2012, after notice the upcoming wvw changes, I have worries as the following.
1) My pride to server is the reason I play, I join zerg/solo roam/defend/scouting/even just running yak for it, no matter if the server is losing or what. Now, If I lose my server identity, I guess I gonna lose my motivation.
2) I play in all different time zone depend on my schedule. Thus I know many people around different time zone, and I can choose whom to play with whoever I know. The new system gonna totally destroy such cognition.
3) The reason I solo play without joining any guild, is that I don't wanna involve in too much politics. In a server since long ago, I have been witnessing guilds born/death/bandwagon...etc, really I believe there is no guild can represent the server community, but the server community live on with many core player identify it as home. In the future, if server will be replaced by alliance, which the alliance sure will be drove by a leader or a group of player, I smell how fishy of the politics in it.
e.g. If you don't play the alliance's meta build/profession, you pretty much will lose your place in it, or even somebody doesn't you, you are out of it. You would never know what will happen to you in an alliance when its driven by people.
4) Some people is saying with the capacity limitation, guilds can not manipulate the game mode as much. However, let say if the cap is 500 , I can imagine there will be alliance recruit guilds to take care specific time zone, like 200 NA + 100 OCX +100 SEA + 100 EU and forming a 7/24 coverage alliance. then if you are in small guild or solo play, how can you deal with such monster?
well, I'm just so worrying since I love the game and the community...
