Okay, back on thread topic.
One very big reason I'd like to see a single LW arena, with large population caps, and larger maps back into the rotation.
MISSIONS.
I have always found in the past that there seems to be a country population threshold to where missions become viable.
In the old MA, I'd say it often was not worth posting a mission unless you had at least 150 players in a country, give or take. If there were that many players in a country, and you posted a decent mission, you could probably count on 10 to 20 players to join up, maybe more.
With the current two LW arenas with small maps and population caps, I often see missions posted that end up going no where. Those that used to post well thought out missions don't much any more, and the rest of not well thought out missions that don't really "take off".
What I see these days are country populations typically below 100, with people begging in text for pilots to join missions.
The split to multiple war arenas and small maps has separated squad mates, reduced good missions to rare events, and reduced the value of strategic targets in the game.
