I'm really curious to know why I have to plant bombs in Search and Destroy, Sabotage, or Demoliton 10 times to get Ninja Pro.
Why not defuse?
I've heard answers from various people saying, "Because if you defuse, it's the same with Flak Jacket, so you can get both perks easily."
But, I have to be honest, I can't really grab the bomb to plant because everytime a round starts, my team mates just run straight and pick up the bomb, even when I message them "Let me pick up the bomb just once."
I'm more better with Defusing because you get to kill the entire team while Planting the bomb is more difficult because without Hacker, you could get detected by Motion Sensors or die from claymores.
Still, many people said that Ninja is meant to go silent. Planting a bomb silently is quite easy, but with all the advance tactics, it's just hard.....Unless you've got a team that can help you.
EDIT: I have Ghost Pro. It's freaking awesome. But, I still get detected by Motion Sensors.
