Yeah I somewhat intended that the carpet bombing (DBombs) couldn't be dropped en-masse but had a timer. Wasn't very clear on that, sorry. But you see in the diagram the equal space between the bombs but the chaotic dispersion, that's what I was implying.
I like the AIX A10 carpet bomb (even though that's incredibly retarded on an A-10

) but one thing that's tricky about MWLL is that, in Battlefield 2 you respawn right away, equip whatever you wish, jump in a newly spawned tank, off you go. In MWLL it's a little more complicated. Dying is sort of a big deal as it can take you out of the game for several minutes depending on map and what kind of asset you need to bring. Even crippling a mech into the red forces it to repair, again taking several minutes out. DBombs would be fairly hard to balance in regards to doing enough damage without being overpowered, how spread out they get, their splash radius, even altitudes. If they disperse too much you force them to be released very low.
I don't think I really intend any bomb except the PBombs to get the pilot kills. FBombs are clearly to break up groups (and break them up they shall), CBombs are for doing moderate to light damage to a large area (and annihilating BAs), DBombs are more general drop bombs. Whether you use them to carpet bomb or not is up to you, they can just as well be used as a single-drop munition. Aircraft have a VERY high 'BULLSHIT!' factor and curtailing that is somewhat my intention. Aircraft can be just about anywhere, they're fast enough (even the Shiva) that you can't really consider any place truly safe from them, and ammo is a non-issue. They flee back to the airfield and in thirty seconds they've rearmed and back in the action. When you give something like the Shiva the ability to one-shot-kill two Assaults every minute? That's where the 'BULLSHIT!' comes in that just frustrates everyone except the pilot.
The idea is to make them support weapons first and foremost, because ground attack aircraft even in the real world exist ENTIRELY to support ground units. An F-15 does not load up with bombs and then go shoot what he wants. He loiters in an area for hours, hitting tankers, until someone calls for help.
DBombs can do some good damage but are fairly imprecise and can't be spammed to guarantee a kill. CBombs do lots of damage to an area but the damage isn't extreme enough to net you kills. It'd basically be the equivalent of an MRM-20 striking every target. Altitude burst ensures you can't drop it 5 feet above an Atlas so that 80 bomblets hit it all at once.
One important thing to keep in mind is that if there's any potential for abuse with a weapon, people will find it and abuse the shit out of it.
