Hi Slayer,
About the charge time, the reason that it will take long time for it to charge is so it can stimulate the Scout plane return to base. Like i said the SCAN is like a scout taking a photograph of the large area of the battlefield. But he still must return to to base safely. It is not always so that the scou pilot would be obedient and return to base on and off. So to make it look like his coming back to base, i suggested that the charge time would be longer.( because it takes time for the scout to land, give the map,and fly again for its next sortie.
Also abut the extra range, i really don't know how to explain this but the extra range comes from the Scout plane. You know the radar thing that detects ground and air troops. Well i am saying that when i CLick "SCAN" the radar thing will expand. The enemies that are detected in SCAN only show them their position but won't constantly track their movements unlike the radar UAV thing from the scout plane itself. So when the enemy is scanned, they will show in the map as static icons.
about the 8 grids, i mentioned that it is for only an example. The devs can do whatever they want for the range.
And i dont want it to scan the whole map, in fact i would like it not to scan the
enemy main base(headquarters). We don't want it to be like vanilla bf2 where its like we just made radar hack minimap legit... its just to keep things balanced and keep the ww2 style of it. We don't want Ambush being foiled by a single recon plane that is not even flying above you and miles(ingame) away. =)
