I feel that the cloak will firstly be a psychological game changer. Scouts with a cloak equipped will be able to lock down certain areas through fear and paranoia alone.

Say that your squad really wants to hold down "B." Simply send a scout or two to B and have them wait. Their superior passive scan range will alert them to when an enemy or enemies are headed over to try to and take the objective. Cloak engaged. Now the scouts lie in wait out of the enemy LOS (to prevent their reticule from glowing red) and wait for them to start hacking. Cloaked scouts move in for the kill with either RE's or a shotgun.

Now you've put fear into those players which if playing in a squad, they will relay that there are cloaked scouts defending B. Suddenly you will have players that may be "too afraid" to enter that objective and it will be effectively locked down.

Yes, I know scouts currently can do this by simply being dampened enough not to show on RADAR and it's terrifying when you're suddenly dead to something that you didn't even see, but cloaks will make this tactic even more frightening and effective.

Now the tactic I described above will bring about a positive change for scouts in another way, they'll actually be needed by teams/squads.

Let's say a squad has set up the scenario I've described above where they are camping an objective watching their passive scans before they cloak. The enemy team now knows from being blown to bits that they're in there but doesn't know how to approach the situation. CALSCOUT I CHOOSE YOU! Unless one of the scouts lying in wait is a calscout themself, the calscout the enemy is sending in "shouldn't" appear on the ambush scouts' passive scans. The attacking calscout "should" be able to see the two ambush uncloaked scouts on its passive scan (remember they haven't cloaked because they haven't seen anyone on their passive.) Calscout now knows where they are, cloaks, and heads in to eliminate two uncloaked scouts trying to "ambush" anyone who tries to take the objective. All clear.

Scouts are going to be used now imo to start doing what their role suggests and scouting out for enemies but mostly other scouts. People will be aware that in their medium or heavy frames, their RADAR will simply not be capable of scanning down scout suits and thus will send their own scouts to assess a situation first before the cavalry arrives so to speak.
