Thanks again for all those who have contacted me with ideas, feedback and suggestions.
I'm going to look at linking some side missions together, so as if you complete the first part of the mission, it unlocks another part. On the latest Takistan map, the "Buzzing" mission now has several parts to entertain as a test, will look to add some more parts to a few of the others and see how that plays out.
Other feedback included limiting squad helicopters to only one at a time, to slow down the gameplay slightly but aid realism. I'm going to have a think about this and see if there is a compromise to be found. I sort of like the idea of a "pilot" class within the squad, but still allow some flexibility. To start with, I've added slot 5 in each squad as (pilot) this has no impact on the squad player (yet) but may help people organise themselves within a squad. Perhaps only allowing the Squad Leader and Pilot to be able to spawn helicopters? thoughts welcome on this topic (and any other).
