This may be an extremely n00b question, but how from callsign emblem or dog tag can you tell in a lobby if someone has rebooted their suit? I'm beginning to notice dog tag surrounds I haven't seen before, and I wonder if that's it?

Synaptic Flare

The emblem with the player's level is a hexagon with anywhere from 1 to 5 V symbols in the center.

Ask, and thee shall receive!

Many thanks, fella.
