Last days I tested some multi missions and my conclusions do not differ much from those who already posted here.
In general the gameplay isn't the same as in V FS2, however I wouldn't describe all the strange events as bugs or bad improvements.
As mentioned above, some of them cause different gameplay and have incredible influence on some missions.
- First expierence (in "Breaking the Seal", a mission by Cet) was a slight touch by a Deimos to my Ares at mission start. Result: hull damage 100%. And I thought Ares isn't made of paper.
- Often a lot of secondaries are necessary to kill one hostile fighter. For instance 10 Trebs for a Basilisk (all of them direct hits), an entire bank of Harpoons for a Mara (most of them hit).
- I also noticed AI are more dangerous than in V FS2. This and the "Treb feature" (or better a feature changed to a bug) have bad influence on game balance.
I guess many new improvements are tested in singleplayer missions, but they have great effect in multiplyer missions. Some missions are not lost, they are LOST. Imagine you are in a multi mission and don't have best connection, in some cases you would give up to play that mission anymore.
