I'm being serious, Devas.
I don't like it any more than you do. I was downright mad when I saw the following:
[Server]: X has called an airstrike on E5!

text notifications might make your teammates aware of the fact that someone has been spotted without them looking at the map every two seconds. and it could be in a different color too.

Are you being serious? I have to check that out :|

Devas, Sham's servers already have airstrikes....

not necessarily text notifications though, maybe spotting an enemy would highlight the square on the grid he's located in for a few seconds. just a general location, nothing exact like bfbc2's 3d spotting.

The "pressing a button to notify teammates where enemies are by grid coordinates" feature is already in the game! All you have to do is press "y" then enter said grid coordinates.

bfbc2's 3d spotting (spot enemy, icon follows him on your teammates' screens) is a terrible feature; it's basically built-in wall hacks. mini map spotting (spot enemy, he appears on your teammates' mini maps for a brief ~1 second moment) is all right, and i kind of like your idea of being able to press a button to notify teammates where enemies are by grid coordinates.

while its a neat idea its nonetheless useless atm untill we add in something that could utalise it like mortars or airstrikes.

Please no...
Edit to under: mortars and airstrikes won't be added either... I hope...

In battlefield you can spot people which makes them show up on your mini map for like 30 seconds or so. I was thinking that maybe that could be implemented in AOS where you could press "Q" and an enemy that you can see would show would show up on your teams map as a red circle for some period of time. Maybe there could be a block distance so that enemies over a certain amount of blocks couldn't be spotted; thus preventing spamming "Q" while looking into the fog. Or spotting an enemy could make you automatically say "Enemy in D5" for example and on your map the square would be highlighted in red for a short period of time. Tell me what you think! Any comments or criticism are welcomed!
