What is "Tenno Affinity"?

[Scylax]

I got this icon in the top right of my screen on the two missions I've played today:

 

When I got it, it said "Tenno Affinity". I know what affinity is, but I'm not sure what exactly that icon is supposed to be displaying. What does it mean?

For a long LONG LOOOOONG time there was a 50m radius from you that anything you murdered or was murdered within that range by someone else- affinity for that kill would be shared between team mates in that range.

Now due to Trinity's blessing making use of that radius for it's functionality it was important players are able to keep track of it. They therefore introduced an icon to tell you how many players are in range of it.

It also serves the purpose of letting you know if anyone in your team- or if you yourself- is hallway hero-ing so you can make sure your squad is functioning well as a group.

In short. Stick together you all get more affinity. If you Lone Wolf, you don't get enough affinity. And if you're Trinity, anyone who isn't near the radius won't get healed.

So always stick together for better results~

It tells you how many Tenno are within the 50 m range from you.  Stick together = more shared affinity.  Hopefully this will discourage people from being hallway heroes if they want free, shared affinity.
