Dont you hate when people leave games? Because I do.
I think that a possible fix for the leavers is, if your team had a leaver, then when you die, you get a faster respawn time.
If two leave, you get a even faster respawn time.
If your WHOLE team left, you insta-respawn.
Times need to be balanced so this doesent give more chances to win for one team or the other. 50-50
Off-topic: Also, I noticed this reading the wiki:
Frostbite (Christmas map, Must be permanent because you can throw snowballs and get the achievement, "Son of a Nutcracker!")

I'd rather have auto-aim removed from Lockdown before they work on anything else. This sounds cool though.
