@Midnight9746That ping is the only recon bit she has. Without it' she's not recon.
Tactical is Skirmisher and Ultimate is Assault.
The ping is her passive and is the only thing that makes her a recon.
As for the tag, there's two notifiers.
A) The glow and circle, and the overhead "Tagged by Vantage" to notify your location is revealed. That is her passive.
B) At the bottom shows the increased damage taken debuff applied by her sniper, which also applies her passive Tag at the same time.
I believe that is how it works now.
I've been tagged without debuff or damage taken before. That means the passive now applies it on ping.
BTW: You are unable to tag ping through windows. Tried that in mixtape.
You must stop aiming and then ping enemy, otherwise it will utterly deny your ability to ping through the window.
You can read their shield and number alive, but if through window you cannot ping at all while they are tracked like that, and must cease aiming to ping through the window.
