There have been dozens of threads about how all hiders should be banned regardless of reason or cause. I've seen those who hide and ambush become the victim of team treason because some punk won't wait for the person to play his game. Bad play and team play abound and demands from bad players to make good ones die are just as plentiful. So why not fix the problem? /TL:DR
I propose, at least on Skirmish, a Surrender/Retreat option. Your team's been humiliated, and you don't feel like being the next notch in some brat's gun belt. Your options are to run out of bounds or suicide, or hide and deal with all the problems we know so well. Therefore let's install an option that the losing few members would be able to either A) surrender or

Here's how Surrender/Retreat would work.
If the teams are mismatched by less than 8 mechs by kill or disconnection, a pilot may opt for Surrender only after they shut down their mech. If this option is selected, their mech is then locked down for 30 minutes. They maintain all their XP from the match but zero C-Bills as if they are captured by the enemy. This will prevent farming by surrendering early in the game to try and farm. Your XP will be the same as the losing XP you would have received, not the winning XP. If your team wins without your help, you still get no CBills and the losing XP.
If the mismatch between teams is 8 or greater, the Retreat option becomes available and the remaining 4 mechs may cede the field to an obvious victor. In doing this, they gain only the losing Cbills, but zero XP. Essentially, you sacrifice the experience, but you keep the money for what you earned IF you had lost as a penalty. Your mech would NOT be locked down because you left the field ceding it to the enemy. Of course, if somehow your team wins inspite of your retreat, you still only get losing CBills and zero XP. Them's the risks you take.
Both options would not be available for the first 2 minutes of the game.

When Repair and Rearm return with Community Warfare, these two options would have more and more value to them. If you surrender, you still have to refit/rearm and cannot access your mech for 30 minutes after. If you retreat, you still get only losing Cbills which makes your profit much lower, if it even covers expenses.
This could be used for all game formats, but right now Skirmish is the one that is all or nothing with no secondary victory conditions, making it ideal to test this theory out. It will increase churn in players getting back into game by preventing 24 mechs from being locked up in a match that ended in 5 minutes and the last smart pilot refusing to give in easily.
There is a minor penalty for opting out early because you believe the game is lost, but if you leave too early, you are penalized the greater by having your mech locked out for twice as long.
The idea could use some tweaking, but I think it would be an honorable (well in as much as this is just a game) way to satisfy many but for the most bloodthirsty.
