Wild idea, a hot take, science fiction if you will - Teamwork.
Let’s think of a scenario: You plan to bomb Redfor bases on Denmark, covered by AA. But because you are not foaming at the mouth about maximum UA, you bring another bomber in so you get one each and spend as little time in enemy areas. You get two attackers with standoff weapons to clear the defenses just before you ingress, giving you a window. But hold on, the attackers can get attacked by fighters… so you bring two fighters to engage. Oh no, but the enemy can have more fighters in the area, so maybe to be sure bring three fighters with you as well. So that is a sortie of 2x bomber, 2x attacker, 3x fighter. Fighters go first to screen and CAP, attackers run SEAD and shorty after, the bombers deliver the payload and head back. Attackers assume a secondary fighter role and provide rear security with fighters until everyone is back at the base to get ready for another sortie. (Spielberg is now calling me, he wants to make this fantasy movie that will put Avatar, Harry Potter, Lord of the Rings, Star Wars and Jurassic Park to shame.)
So we as players have all the tools to work around this EvPvEvPvP problem. If there is more bases, you bring more bombers, if there is more AA, you bring more attackers, if there is more enemy fighters… you bring more fighters. But at the same time the other team is trying to do the same and we arrive at the zero sum game.
In the real world of WT airsim though, figters will go to where the enemy is, not friendlies. If there is a constant furball in the middle of nowhere, they will go there to get kills and SL. While this happens, attackers will go for the ground battles to get ground kills and SL because all the fighters are occupied with the furball. Bombers pick up whatever bases to they can sneak up to and try to get as many as possible to get tonnage and SL. Inversely, bombers will not go for the bases covered by AA because it’s certain death, attackers will not attack the AA, because it’s way more dangerous than ground battle and fighters cannot afford flying 20 minutes escorting when nothing can happen. The game does nothing to incentvise teamork, there is no Tank-DPS-Healer dependency like in the MMORPGs, there is no rock-paper-scissors system. Just keep doing whatever you are doing until someone runs out of tickets or the timer runs out. Also no incentive to help anyone on your way back home for that sweet UA bonus. Others can get missiles up the engines all day (probably don’t even have to worry about going negative from prem time), so why would I waste my non-prem hard earned SL.
There aint no way in hell that random people would cooperate to such degrees. Clans/Communities maybe, but even then they will some someone else getting all the kills while they “help win the game” but get nothing in return… So they go “help” the fighters to get some kills and SL… and we are back at the start.
