Some of the benefits of the system are outweighed by the clueless dolts- HO collisions still occur, with both planes being destroyed, even if only one goes down due to the collie of death, and one to guns. But, at the same time, the guys who fly with no regard for anything are more likely kill themselves than their intended target- I've gotten lucky many times this way. You probably all have- ever gone AFK and come back to two kills while you were on autoclimb? That's the collision model doing something useful.
Bombers... I don't think I need to repeat my feelings on formations as they are modeled. I would wager that bombers cause more collisions than they fall victim to. I don't care about any disadvantages that may result where formations are concerned.
I like the current setup- although it can be extremely frustrating. I've attempted to force collisions on a number of occasions, and while I won't claim that it's easy to replicate, it is not impossible. It does require a great deal of luck, and is fruitless more often than not. I don't think it can be abused, unless you have a stable connection, and are fighting the same people, with stable connections, and the ping times of all involved would have to remain the same. That just doesn't strike me as something that happens regularly in the MA. In the DA, maybe, but chances are if you're in there fighting the same guy repeatedly, you're not looking to call in the collie of death to get a kill.
Some of you are just being argumentative- I've known dedalos for a while, and he's not an unintelligent guy. Yeah, his typing sucks (hey, he writes coad. You know how those guys are... ), but he's not stupid. Just incredibly stubborn.
