People prime it so it acts like an impact nade.
So? you still need planning to know when to prime it. It's a good job that you can't prime whilest shooting, though.
Theres a function where you can make your team un specable?
I think what you mean is where you have to use the chase-cam on your own team. There is, but it's not very effective cos you can go to a wall, and the dude speccing you can look around the wall for you and tell you if someone's there using the free-rotate cam. Also, it takes the fun out of it.
recon takes some typing (or binding) skills to work effectively
First of all you cant die from chasing a timed nade and sitting on it.
? I've done it loads of times, killing myself with a timed grenade. easy. I don't usually do it on purpose, though so that I can lose the round
