"Invisible" perk and crowd gamemode?

[DeltaStrikeOp]

Duuude, awesome ideas!

I'm afraid the "invisible" perk would be too OP. I play Halo 1 PC sometimes when there aren't ACR games, and the invisibility power-up is simply too OP. You can't see them at all. If you can't see them, you can't shoot them. This perk would be even more powerful than recon+hands+steady+vision, LOL. But it would be interesting since almost nobody uses the "ninja" perk. Maybe if it were a killstreak that you activate with a key-press like airstrike and if it were to last about 3 seconds then that'd be cool.

Your idea of having basically assymetric operations sounds very cool! It would mirror how sometimes Special Forces operators go in with local garb to carry out their objectives. This would also be similar to how "Project Reality" is played too. There is a "Rules of Engagement" you have to abide by saying basically that you cannot fire on civilians unless they heal insurgents or throw rocks/objects that can maim against the BLUFOR.
This does bring up the question of when you would be able to shoot the bots when they start to knife you. Also, what happens if both sides use only knives? How would you ID the enemies? =/ It could be a very long round of running around with knives basically going like, "SWING FIRST (explicit), SWING FIRST!".
