We all know being an Observer is like being the Commanders plaything. Constantly having to endure the game shouting at us "Observer!!! Come Here!" "Where's my Observer!".
What if instead of using the stick, we used the carrot and made being an Observer more interesting and fun, by giving the Observer additional responsibilities when calling in certain supports.
The suggestion is this: After the Commander calls in certain supports (non mortar) on a location, the Observer is then required to choose a DIRECTION for that call before it gets sent. (possibly using a popup rotary wheel with all 8 cardinal directions on them, unless a better/quicker/funner option is available) In addition, for insurgents it would be the on-site Observer who pilots the IED drone (lets be honest the AI controlling that thing is terrible).
This would greatly increase the sense of accomplishment for Observers (instead of just being forced to play your part by being near the commander) and would increase the sense of teamwork between the Observer and Commander.
This would also have the added benefit of removing the randomness/luck of getting a good attack direction when using A-10 runs, drone bombing-runs, Attack Chopper rockets, etc.
