The Drifter Intrinsic "Herd Travel" (rank 10 in the "Riding" tree) is more difficult to use than necessary because on the Duviri overlay map, player icons are not differentiated in any way; instead, every player is denoted with the same round blue icon.
In full four-player groups, this makes it needlessly difficult to pick the correct player for teleportation. The whole idea, after all, is to teleport to the correct person in the squad.
Therefore, players should be differentiated by displaying their glyph, and preferably also by showing their name under their icon on the overlay map.
