Here are my criticisms.
Needs some sort of window to view the currently selected items before starting operation
Needs an easier way of selecting/deselecting items and getting operations started. Voting works but with several players it can be confusing and slow. Some "ARMEX organiser" who gets 100% control over it would be good.
Needs a "playlist" for operations. Sometimes you want to play 3 survival missions, then a Defend mission, etc, not just start at Survival and work your way through the list 1 by 1.
We played earlier with a T-90 selected, unfortunately it spawned with crew inside which were OPFOR so they killed us at the spawn point. Suggest spawn all selected vehicles empty, it's multiplayer after all, you're playing with a human crew.
Sometimes the vehicles are spawned too close together on operations and explode instantly.
This is especially true of helicopters and jets
Jets seem to be spawned "flying" at 0 altitude and therefore crash instantly
If a jet is selected, all the players spawn on foot 4km away from the target with one jet (which as previously mentioned, explodes). Suggest spawning the troops at 400m from the objective and spawn the jet 4km away, in the air, flying.
Some issues to work out, but I've had some really good fun with this mission so far! :)
