Currently it's not worth to rtb even with the reward for it, unless you are low on money. Destroying a lot of targets and instantly "teleport" back to base is way more effective.
I believe it's always possible to make realistic behaviours the most optimal and fun way to play with the right game mechanics.
RTB
Players should not get rewards for their kills unless they return to base. If they eject they only get the reward if and when their pilot gets rescued.
This could be an optional rule in the map settings.
But I think after getting used to it this would make the game feel more exciting as it brings the focus more on survival.
SAR
This would make search and rescue way more important and rewarding. When saving a friendly or enemy pilot the rescuer should get a cut of their kill reward. You can think of the pilots as bags of money. When a plane is shot down after a particularly good run it becomes a race to get the pilot.
Not everyone likes to do SAR so the AI should do it as well. Scout cars should go out of their way to save pilots. Also small boats should be added in the future to help on the water. AI Helicopters. Not to mention players can already give orders on the map to vehicles to approach their pilots.
**Why is this better than the limited lives suggestion? **
I'm not opposed to the teams having limited lives like in Battlefield. It could work well with this system.
But limited lives can be ignored by players that don't care about team play. Also just with limited lives suicide runs are still worth it if you kill at least one enemy player. It only punishes teams that have inexperienced players.
Getting payed only after RTB cannot be ignored because it effects the player instead of the team. And the more you kill the more important it becomes to be careful. It works more as a risk-reward system.
Isn't this too punishing?
Low tier planes and helicopters for SAR should always be available from passive income and requisition.
