I'd like to see a command that tells a bomber to immediately drop a bomb if its off cooldown.
It should also have a toggle option that, while enabled, lets the bomber drop a bomb whenever it is off cooldown.
This should be easy to implement, and open up a wide array of options not available now.
One problem I get with bombers is in attacking large armies. The bombers pick a 'random' target and try to engage it, and if they fail they throw nothing at all. However, if they had dropped a bomb it would probably have hit 2-3 enemy units.
Ideally, bombers should be able to do carpet bombing, take targets of opportunity, etc... but this is hard to implement. The drop bomb command should give players the option to do all this with only minimal micro.
