If we can get bombs to act like physical objects which can be destroyed by AA and such I'd be less hesitant for the idea of large damage.
If I'm walking and get hit by a bomb without realizing it as an infantry it's going suck. If I hear an audible whine of a bomb as it's coming down and can react to it I'm less inclined to think it's a cheap tactic. (This has been covered in the artillery threads to death).
This is one of the big reasons I want velocity inheriting bombs such that dropping them causes a natural acceleration. At that point (with a sane minimum drop height) you can allow players to lock onto them or shoot at them if they want. If you dive bomb the velocity inheritance will essentially throw the bombs into the targets making a huge difference between high altitude bombing and dive bombing.
Not sure if you guys saw the recent
Battleship movie? That kind of tactical teamwork of player countermeasures against vehicles is something I really want in the game.
