Hey its me from the thread on Reddit. If I where you I would change a few things involving the Missions and the Faction System. Ill start with the Missions.
The way the lore of chernarus works, much of the UN force was occupying the south west portion of the map, but remnants of the CDF still roamed trying to find their way out of the north to other parts of Chernarus. If missions were to involve small groups of CDF or Chedaki it would make a little more sense. Other than that Missions aren't necessary, or at least not frequently. If you do one mission a restart it would be nice because people would actually be worried and try to get the stuff in it, leading to More encounters.
Factions: The Factions system you have in place right now is slightly flawed in my opinion. Player factions should take importance, or atleast the factions offered by the server should vary slightly. Taking note from the Old DayzRP groups which aim to replicate and form groups which fall in with the Chernarus Government or rebels. Ill name a couple as an example.
Chedaki: Old rebels which lost and went into hiding after the Civil war of 2009. They have always been just active enough to be remembered.
Ultra Nationalist Party of Chernarus: The nationalists where a radical force fighting not just the chedaki, but instead the Russian civilians of Chernarus.
CDF: Pretty self explanatory, the Chernarus army which has fallen apart, but some isolated divisions / groups remain.
Civilian warlords: People who may have fought before, or participated in some sort of combat which granted the the know-how to become powerful leaders in the ever present apocalypse.
Russian Forces: The Russian military would have intervened to assist the people escaping and might well have failed, so remnant of battalions trapped past the blockade of chernarus would have to fend for themselves, with certain vehicles and supplies being granted to them from the start.
Thats just a few Ideas, but I still and will always think player created factions should take president over any others.
