This is my take on it, personal opinion only...
ArmA 3 is in a state of flux. It's still having new features added (fatigue, weapon sway, muzzle mechanics etc).
This causes mods to quickly go out of date / break / regularly change.
In particular the medical systems are extremely difficult to get right.
No one mod set has been universally accepted yet; people are still holding out psychologically for the magical ACE or ACRE's to be released, expecting them to be golden bullets.
Given these difficulties I don't believe it is currently possible to find a stable set of mods that are guaranteed not to change, even in the short term. This makes mission creation tricky to say the least.
Goodson is trying to get @3CB tied down with the Op Killwave trials (this week and again next week). Clearly a defined set of mods which don't change is what mission designers need, but I'm slightly pessimistic that this will be achieved during the next few months because of the reasons given above.
I have stated it before, but I believe we need a public server coordinator, in the same way that we have a private Ops coordinator. Without this coordination, we end up in the mess we have today.
From my perspective, I've been working on Capraia, and because it uses TFR and CSE, I didn't feel it could go on the public server, because it uses "non-approved" mods not on our
mod page. Hence I put it on the DEV server for people to play with and see what they thought of TFR and CSE - it's been quite a bit more popular than I expected and has become the de-facto mission for the day. The DICE mission is also nice, but again requires a completely different mod set, hence it's not on PUBLIC either.
No one else has taken on the update/creation of the public server missions, probably because of the bugs in ACRE and AGM, and the feeling that we won't be using them for much longer anyway, so why waste the effort?
SummaryIt's currently a difficult time for mission designers, but with very exciting prospects as the game matures.
Keep existing members happy and don't worry too much about recruitment until we have a more stable platform.
