What do the colored numbers mean that appear next to names in the after battle stat page?
Do you have a photo?
I’m going to assume its the numbers from you having the “Group is Recruiting” or whatever its called function activated. Its the box above or below the “Join Any Team” box.
If this is the case, its because you have “Group is Recruiting” activated, so when you play a match you and three other people will be grouped into a random stack during the match.
What you’re referring to is, most likely, the squad identifiers. If you have the option selected to automatically create a squad with random teammates, those numbers (1-4) are the indication that they were your squad members.
The same numbers should appear if you open the scoreboard in the middle of a battle.
I don’t know what the blue box numbers signify, but I almost always end the game with a number 1 through 4 linked to my name.
