Hmmm. I don't use the generated tasks too often myself but I hear what you're saying. I'm sure they could use a little bit of work. I went through them all awhile back and made some reports and I was under the impression they all should do just fine for the most part now but apparently not. :(
I personally prefer to patrol and recon and leave my fighting open ended - making "missions" myself, aside from the occasional task request every once in awhile when I get bored (you can make or request a task in the tasks menu in the ALiVE menu).
The insurgency I linked has the auto tasking turned off (but again, you can request a task at any time). It's designed for you to patrol and hit the enemy AO, blowing up insurgent HQ's, etc.
As I said it might need some balancing (more enemies, less enemies, etc). But it's a good start. If you try it let me know if you have any suggestions (relating to balancing, mainly. But I'll take any feedback).
If I get some time I'll go back through the auto tasks again and make some new reports on it, but sadly, if there are issues, nothing I link you will fix it.
