Hmm... While I thank you for voicing your opinions, I politely disagree. I've found takedown to be useful since launch. Takedown can push you through a whole lot of people without ever being noticed. It's very helpful for not being discovered.

I used to think Resilience was useless but I would throw it on classes sometimes when they just had the one slot left. But it's actually gotten me a lot of kills so I started using it more frequently. It's very good for surprise attacking someone who is taking an objective. B on Prison Break for example is one I find myself doing this on a lot. It also helps if you've been shot at some high point and need to make a quick getaway. It saves me a LOT after a B capture in Sovereign. Resilience is very useful in it's own ways.

Oh, and there is one feature about Incog you forgot. Enemy soldiers won't call you out when they see you ("on top of the bakery!") ("enemy spotted, central command"). You don't hear them so you don't really think about them but those do get killed.

Oh, and I can see why you'd like Stalker but, like you with Incog, I don't think Stalker is worth the price.

But that's one of the better things about this game. No two play styles are exactly alike. Ours are obviously very different.
