Overkill game mode - I like it!

One thing I dislike in overkill is teamspawn. Its ok in games with 4-6 players, but for example 8-8 games are just ridiculous. There are mobs of players slowly moving through entire map dieing and spawning at the same time. Anyone who is afk-ing outside enemy base is a spawn point, its just a matter of seconds, the best players respawn and you have lost.
Also its sometimes too easy, you can run through entire map just to be killed at random by spawned enemy, skills are half-useless, anyone can kill you instantly, that's why i never considered minstagib to be the main game.

I would recommend changing behavior of teamspawn or lowering player limit.

Maybe spawn with, eg. 2 AP which die down at the same rate as 5 HP from a shard. In other words, you could survive a nex hit for first 2 seconds.
