There's already a loud sound that plays when you decloak.

Problem is it's hard to hear when you're not the one decloaking, even when the person is right next to you.

No, that ruins the stealth element of the cloak.
A .5s delay would be better

So everyone is saying that cloaks are too effective, especially when combined with a shotgun scout. So here's what I think, the main reason why people are annoyed is because of the fact that with cloak, you will always get the first shot, this is especially game breaking when using any OHK potential weapons, whether it be nova knives (yes I said it) or shotguns.

Now you could tell people to be more aware, but this will never work, some people are just blind. That being said, I propose boosting their awareness, no nerfs, just make it so that whenever a guy have their cloak active, a buzzing sound will give out their location (a good suggestion that I heard from someone before 1.8). This way cloak field wouldn't need a switching nerf, good players would simply try to deactivate their cloaks when near an enemy.

The buzzing sound should give away cloakers of 20 meter range, getting louder as they close in, it should work with environment headphones too (or whatever you call these things). So what do you guys think? Boosting awareness is the better option in my opinion.

This wont help at all.

Why?

Well, with 20mts ''buzz'' sound range, a player will be hearing this noise ALL game, making it REALLY difficult to detect cloked enemies based on noise alone.

Then after you and your QQ buddies realize you are still dying, will propose ANOTHER nerf,

this will end, as with everything with CCP, in a HEAVY + Unnecessary NERF.

So just leave it as it is.
And learn to live with it...

Cloaks were never intended to be a OHK offensive tool, chiefly because they weren't needed for it...a quality scout has always been able infiltrate enemy territory and lay waste to the enemy from the inside without the cloak. It was meant to be a tool to make stealth tactical relocation easier. I'm certain I recall a dev saying something along those lines but I'm at work between clients and haven't the time to dredge up the specific post.

I routinely wreck proto heavies with a MLT Minmatar Light Suit, MLT Shotgun, MLT KinCat & CardReg, with a R-9 Drop Uplink and a MLT Submachine Gun as my Sidearm.

That is NOT OK.
