While this problem occurred also in Reach, it didn’t happen near as much. Now that we have ordnance drops (AKA, care packages facepalm) this happens much more often. It’s not really a noob type of a move, nor is it pro. If I was a stealth type of guy, I would probably do the same thing.
It all comes down to 343 and making a broken game. I miss Bungie 
Here’s to hoping that 343 won’t be stupid enough to add active camo in Team Snipers.
