Stealth Missions?

So a few times I’ve played on my own; 1v1 against a Predator, and it’s tense, I love it.

But there is a critical gameplay flaw.

What’s the point of being stealthy if certain objectives alert enemies of your position.
It’s a problem because now they know there’s someone around instead of being oblivious, and forces players to fight.
I know it sounds silly to be complaining about no fighting in a Predator game, but believe me, it was tense enough and works great for a 1v1 against a Predator.
I was covered in mud, he was on top of me but couldn’t find me, I was doing my objectives, and he was looking for me, very close, but unfortunately I had to plant a receiver in an open field, and I did it without being seen.
All of a sudden every enemy knows I’ve arrived and the Predator knew where I was because I had no choice but to fight.

Imagine instead of every enemy being alerted of my position, they are just searching. They don’t run up to my position, but they wander. I still have to remain near the objective and hope for the best, instead of having enemies charge my obviously secure hiding spot.

It just seems that if I’m going to be in a 1v1, which happens a lot, the stealth portion of the game needs to be fine tuned, because enemies should not know where I am hiding after completing an objective that alerts them.
