I would have an idea for a new or an additional spotting system: basically, you'd make the enemy flash on the minimap for your entire team, should especialyl be helpful for your pilots.
I realize that this is a very powerful otion, so I suggest that to do this, you have to wear some sort of heavy radio, which forces you to become stationary while spotting, and you have to hold your crosshair on the target, with a "lock-up" period of two or so seconds (i.e. you have to hold your crosshair two seconds on the target5 ebfore it will get marked). This way, moving targets are fairly save, while enemy campers can get zeroed in and taken care of. Especially those campers in tanks...
BF2 already has that system.
Sorry again, never played BF2 obviously. Modern war doesn't do much for me.
Ya should at least give the demo a go since you'll be buying the game eventually if ya plan on playing FH2. ;)
