[Mission building] Running into various problems...

Sup all, Past week or so I've been working on my custom Mission and learning the full in and outs of editor. I've been reading forums, ArmAHolic, BiS editing section, whole nine yards.

I have managed to learn basic scripting, and getting them to work via Trigger. So far I have IED_Man and Sandstorm scripts in the mission, both I got working with a few "dohh homer moments". I have a basic in-game music trigger set up to fade off once players leave the FOB or fire a single shot with their rifle. I was able to mess around and make them somewhat random with the Waypoint "proximity" i think its called, to spawn them in random (at-least I think thats what it does, i hope)

I got to a point I felt my Mission was pretty rock solid. I had numerous triggers doing avg simple task, had First Aid and Support fully working, and along with my own custom made CAS. With chopper insertion and a little FOB i made.

Problem's I run into though, I experience in MP / CO OP when my buddy and I run it. This is why its so frustrating, I can test all day and night in the editor and things run great, export to MP, load up a server and play, Animations are broke, some odd Trigger cuts off my music too early, The fact I can't find a skill lvl to have my enemy AI on to best act like Insurgents that they are. And my #1 problem, Finding that balance of Realism (Number of enemy in the area) vs Mass enemy to make things crazy and body counts up (which is what me and my friend enjoy when its just us two). The mission was at a point it was impossible, so I cut numbers by 2, and still too many, than you add in too many friendly AI and they all go retard mode, makes less fun and harder to lay down bullets.

Just tonight after a week of tinkering, my buddy and I sat down and played it through, which much better results on number of enemy AI, but I could tell he was sorta bored. Sorta due too when its too many group AI its just too much and they drop quickly. Also mostly due to my Apache just decided to go from town to town and kill all AI, so it was a waste of a run when I we got to 2nd objective, and 3rd, to the enemy training camp.

I think what's going to have to happen for realism is, place a grp of bad guys, un-formation them to put them in exact spots, and also some on a Move/Cycle waypoint for Patrol, but I have no clue how to put AI in buildings, or say a weapons cache in there. (Sorta like a mini Insurgency mode for 2 ppl)

Any tips/help for my problems? My Latest build that I ran tonight Link

Suggestions, Hate, Improvements, Dislikes, all welcome. I'm learning, and it's something I can't stop, its addicting this Editor, you can build whats ever in your mind, and I love it.
