Sounds like AvioDev still has quite a bit of work to do on Multiplayer. And I imagine there a number of tidbits yet to be completed. It's still beta but I'm really glad they've released what they have so far.
I'm not a subject matter expert but I'd say, as a trainer, it's a feature of the aircraft whether you're flying solo or have an instructor. I don't know if the CC version has it as well. I guess Vibora will have to chime in.
Just wanted to make sure because the change log didn't mention it, ie.
Multiplayer- Now you can take control in rear cockpit. Some system works (Gear, Flaps,Stick, Pedals). WIP.
One thing about the mirage, and maybe it's been fixed, is the bombing doesn't seem to be very accurate. I like A2G myself so that kind of turned me off a bit.
I do too in DCS but mainly because I find it really distracting when I'm messing around in the mission editor or doing other stuff in the GUI. Some of the module tracks I really like but some I kinda hate. Won't mention which ones to be polite.
