I've said in the past, and I still think that I'd prefer a more "impactful" damage system... but the key is, what does it do to gameplay? I think the positive impact to gameplay on a more granular system would be immersion. We DO have to be careful however of not making it too complicated, or it will never get implemented, AND have to keep in mind that this method would affect not only all planes, but GVs as well.
My thought was... right now we've got 2 "states", green(0% damage) and red(100%). It might be beneficial to go to a 3 or 4 "state" system... i.e. Green(0%), Yellow(50%), Orange(75%), Red(100%). This system could actually work WITH our current system and apply ok across all "objects" if applied properly. Here are some thoughts on how this system would work :
Wing - Green = 100% lift, Yellow = 87.5%, Orange = 75%, Red = Gone.
Aerilon, Rudder, Elevator, Flaps, Gear - Green = 100% actuation/deployment speed, Yellow = 75%%, Orange = Stuck, Red = Gone.
Engine Oil / Fuel - Green = No fluid loss, Yellow = slow fluid loss+ small thin smoke (black/grey) trail, Orange = Medium leak + large black trail (similar to Red in our current damage system), RED = fluid dump, large "sputtering" trail. Of course when all oil is out it hits RED mode and starts damaging engine.
Engine (AC or GV) - Green = 100% good, Yellow = 87.5% power, Orange = 75% power and (sound change for cylinder misfire), Red = Dead as now.
Weapons - Green = 100% perfect, Yellow = 12.5% misfires, Orange = 25% misfires, Red = Dead as now.
Tracks - Green = 100%, Yellow = 87.5% speed, Orange = 75% speed, Red = Dead i.e. "Tracked"
Turret - Green = 100% rotation, Yellow = 87.5% rotation, Orange = 75% rotation, Red = "turreted"
This would not require changes to the current hit box structure, and WOULD make weaker weapons have an impact. In a gameplay aspect, in some ways, it could create a more "timid" style of flying, but at the same time, if you fly too timid, you could be damaged enough to the point where your only egress would be to fully engage and destroy the enemy. It would increase immersion by making every part of your vehicle/aircraft count which might actually LOWER the chances of collision and less chance of a HO attempt.
